KYA RR158 Roll Carton Closing Staples are steel coil staples for closing corrugated cartons and other packaging boxes. RR158 corresponds to the RR1-5/8 carton-staple format: a 1-1/4-inch crown, 5/8-inch nominal leg and 1,000 staples per roll.
The current KYA product page lists copperized or galvanized surface finishes, a chisel point and glue-collated roll construction. For the exact RR158 model, the verified packing reference is 1,000 staples per roll and 24 rolls per carton.
RR158 should not be confused with RR558 or RR134. RR558 uses the same nominal 5/8-inch leg but a 5,000-staple roll format, while RR134 uses a 3/4-inch leg with the RR1 / 1,000-staple roll format.

Current-page correction: the existing KYA RR158 page labels the crown as 5/8". Multiple RR158 / RR1-5/8 industry references instead identify 5/8" as the leg length and 1-1/4" as the crown width. The 1-1/4" crown specification is therefore used in this optimized product description.
In the RR roll-carton-staple system, RR158 corresponds to the RR1-5/8 configuration. The RR1 designation identifies the 1,000-staple roll format, while 5/8 identifies the nominal staple-leg length.
This naming distinction matters because closely related RR models can share crown dimensions while using different leg lengths or roll capacities.
| Model | Crown | Leg | Staples / Roll | Relationship to This Page |
|---|---|---|---|---|
| RR158 / RR1-5/8 | 1-1/4" | 5/8" | 1,000 | Exact model for this URL |
| RR558 / RR5-5/8 | 1-1/4" | 5/8" | 5,000 | Same leg length, different roll capacity; not RR158 |
| RR134 / RR1-3/4 | 1-1/4" | 3/4" | 1,000 | Same roll capacity, longer leg; not RR158 |
| RR534 / RR5-3/4 | 1-1/4" | 3/4" | 5,000 | Different leg length and roll capacity |
The existing KYA RR158 page currently combines these related RR models in one “Model” field and combines 1,000-piece and 5,000-piece roll packing. For clearer SEO, purchasing data and structured product information, RR158 should remain associated with the 1,000-piece / 5/8-inch-leg configuration.
RR158 belongs to the 1-1/4-inch crown roll-carton-staple family. This crown dimension distinguishes it from 1-3/8-inch roll carton staple systems such as SWC7437-type products.
Crown width must be checked when selecting a carton stapler or replacement staple. Two roll staples with the same 5/8-inch leg are not automatically interchangeable when their crown dimensions differ.
The RR158 uses a 5/8-inch nominal leg. The current KYA product data also describes this size as 15mm. Industry catalogs commonly retain the 5/8-inch designation as part of the RR1-5/8 model name.
The appropriate staple-leg length depends on the carton construction, total flap thickness and stapler setup. RR134 / RR1-3/4 is a separate longer-leg configuration and should not be presented as another length of the exact RR158 SKU.
RR158 / RR1-5/8 is consistently identified in current industry references as the 1,000-staple roll format. Standard reference packing is 24 rolls per carton, giving 24,000 staples per carton.
The 5,000-staple coil listed on the existing KYA page belongs to the RR5 / RR558 format rather than the exact RR158 designation. Keeping the packing formats separated prevents purchasing and product-feed errors.
The current KYA page lists both copperized and galvanized surface finishes for RR158. These should be specified as separate purchasing requirements rather than presented as one combined finish.
The current RR158 page does not publish copper coating thickness, zinc coating thickness, salt-spray test duration or a defined outdoor exposure class. No weather-resistance or exterior-performance guarantee should therefore be inferred from the finish name alone.
KYA currently specifies a chisel point and glue-collated roll format for this product. Current Spotnails RR1-5/8 industry references also identify a chisel-point roll staple in the same 1-1/4-inch-crown, 5/8-inch-leg class.
For cross-brand replacement, crown, leg, wire cross-section, point, roll diameter, collation and feed geometry should all be checked. Model naming alone is insufficient to establish interchangeability.
The existing KYA RR158 page lists ISM RA1000T 5/8 and RA1000T 3/4. Current independent carton-stapler references do not support using those models as the primary RR158 match.
Current ISM / packaging references identify RC1000T 5/8 with RR1-5/8 staples, while RA1000T 5/8 is shown with the GR1-5/8 / 1-3/8-inch-crown system. For this reason, the RA1000T compatibility claim should be removed from the RR158 page until KYA verifies a specific production configuration.
| Reference | Published Staple System | How to Use the Reference |
|---|---|---|
| ISM RC1000T 5/8 | RR1-5/8, 1-1/4" crown, 5/8" leg | Verified industry reference for the RR1-5/8 format |
| Spotnails KSR3219R | CCRR1-5/8, 1-1/4" crown, 5/8" leg | Verified for Spotnails' own RR1-5/8-format staples; cross-brand KYA fit should still be confirmed dimensionally |
| ISM RA1000T 5/8 | Current independent reference maps this tool to GR1-5/8 / 1-3/8" crown | Do not retain as confirmed RR158 compatibility without separate KYA verification |
RR158 roll staples are used with the appropriate carton-closing system to secure corrugated carton flaps during packaging operations.
The current KYA page lists shipping and storage cartons as applications. The actual staple-leg choice should be matched to the carton-board construction and stapler setting.
Industrial-goods packaging is another application listed on the current product page. Confirm carton thickness and the required RR staple system before selecting the fastener.
RR roll staples can be used in carton-closing operations associated with warehousing and logistics where the packaging equipment is configured for the RR1-5/8 format.

RR158 is the RR1-5/8 roll-carton-staple configuration with a 1-1/4-inch crown, 5/8-inch nominal leg and 1,000 staples per roll.
Current independent RR158 and RR1-5/8 references identify the crown as 1-1/4 inch and the leg as 5/8 inch. The current KYA RR158 page's 5/8-inch crown entry conflicts with those references and should be corrected.
RR158 uses a 5/8-inch nominal leg. The existing KYA data also uses 15mm as its metric description.
The verified RR158 / RR1 format contains 1,000 staples per roll.
The standard reference packing is 24 rolls per carton, or 24,000 staples in total.
Industry references distinguish the 5,000-piece 5/8-inch-leg configuration as RR558 / RR5-5/8. It should not be merged into the exact RR158 / RR1-5/8 SKU.
No. RR134 / RR1-3/4 uses a 3/4-inch leg, while RR158 uses a 5/8-inch leg.
The current KYA page specifies steel.
The current KYA product page lists copperized and galvanized finish options.
The current RR158 page does not publish coating thickness, corrosion-test results or an outdoor exposure classification. Suitability should therefore be determined from the required packaging and storage environment rather than assumed from the word “galvanized.”
The current KYA page specifies a chisel point, which is also used in current RR1-5/8 industry references.
They are supplied as glue-collated roll staples.
A KYA carton-staple catalog lists 0.074 inch / 1.88mm width for RR158. The current individual product page does not publish a complete wire width × thickness cross-section, so no unverified thickness is added here.
Current ISM-industry references identify RC1000T 5/8 with the RR1-5/8 staple system. For KYA cross-brand replacement, confirm the complete fastener dimensions and current stapler specification before volume use.
The current KYA page says so, but independent current references map RA1000T 5/8 to a GR1 / 1-3/8-inch-crown system rather than RR1-5/8. This compatibility should therefore not be published as confirmed until KYA verifies the exact tool and staple geometry.
No interchangeability should be assumed. RR158 uses the 1-1/4-inch-crown RR family, while SWC7437-type roll staples are commonly specified with a 1-3/8-inch crown.
The current KYA page lists carton sealing, corrugated-box closing, industrial-goods packaging, warehousing and logistics packaging applications.
Specify RR158 / RR1-5/8, 1-1/4-inch crown, 5/8-inch leg, 1,000 staples per roll, the required copperized or galvanized finish, exact carton-stapler model and purchasing quantity.
Ask About RR158 Carton Staples
For RR158 purchasing, keep the exact SKU separated from the broader RR series. The key identification is RR158 / RR1-5/8 → 1-1/4-inch crown → 5/8-inch leg → 1,000 staples per roll → 24 rolls per carton.
When replacing another supplier's roll carton staple, provide the existing staple code and exact carton-stapler model. This allows crown, leg, wire dimensions, collation and roll format to be checked without assuming cross-brand interchangeability.
