KYA 18 Gauge 4K Series Narrow Crown Staples are designed for professional woodworking, cabinetry, furniture production, paneling, trim and upholstery fastening. The product family is marketed as a 1/4 inch narrow crown staple, with a published crown dimension of 5.7mm and a wire section of 1.25 × 1.05mm.
The standard 4K Series range includes 410K, 413K, 416K and 419K, covering leg lengths from 10mm to 19mm. Galvanized high carbon steel and stainless steel material options are listed for the product family. Buyers should confirm material, finish, staple length and exact stapler model before ordering.
The following dimensions describe the published KYA 4K Series staple family. When replacing an existing staple, compare the complete wire section, crown and leg length instead of relying only on the 18 Gauge or 1/4 inch description.

The published packaging information for the standard galvanized 410K, 413K, 416K and 419K models is shown below. Confirm packing before ordering if your purchase requires different material, labeling or carton configuration.

|---|---|---|---|---|---|
| 410K | 10mm (3/8") | 100 | 5,000 | 20 | 50 |
| 413K | 13mm (1/2") | 100 | 5,000 | 20 | 50 |
| 416K | 16mm (5/8") | 100 | 5,000 | 20 | 50 |

The standard 410K, 413K, 416K and 419K packing table lists a galvanized finish. High carbon steel provides the mechanical properties required for staple forming and driving, while the zinc coating provides corrosion protection compared with uncoated carbon steel.
The suitability of electro-galvanized staples depends on the exposure environment. Confirm the required coating or material where moisture, treated wood or other corrosive conditions are involved.
Stainless steel is also listed as a material option for the 4K Series product family. The current product description references Grade 304 stainless steel. Buyers requiring stainless steel should confirm the available grade, staple length, finish and packaging when requesting a quotation.
Stainless steel should be selected according to the actual exposure conditions and project requirements rather than treated as interchangeable with galvanized high carbon steel.
The narrow crown and 18 Gauge wire format make 4K Series staples useful for professional fastening where a relatively discreet staple crown and controlled fastening area are required.

Select the staple length according to material thickness, required penetration and joint design. The longest available staple is not automatically the correct choice for every application.
KYA lists the following tool-series references for 4K Series staples: PREBENA E, ATRO 90, SENCO L, DUOFAST 1800, FASCO 90, HAUBOLD 6000, HOLZHER C, MAX 4MA, NIKEMA 90 and SPOTNAILS 48.
These references should be used as a starting point for tool matching rather than confirmation that every model within each brand or series accepts all 4K staple sizes. The stapler should accept the required 18 Gauge format, 5.7mm crown, 1.25 × 1.05mm wire section and selected leg length.
If you are replacing an existing fastener, provide the exact stapler model and current staple designation when requesting a quotation.
Confirm that the stapler accepts 4K Series or a dimensionally compatible 18 Gauge narrow crown staple.
The published 4K Series crown is 5.7mm and the wire section is 1.25 × 1.05mm. These dimensions provide a more reliable compatibility check than the nominal 1/4 inch crown name alone.
Choose 410K, 413K, 416K or 419K according to the material thickness and required penetration. Confirm that the chosen length is accepted by the stapler.
Specify galvanized high carbon steel or stainless steel according to the operating environment and project requirements.

The published KYA range includes 410K at 10mm, 413K at 13mm, 416K at 16mm and 419K at 19mm.
The published crown dimension is 5.7mm. The product family is marketed as a 1/4 inch narrow crown staple.
The published wire section is 1.25mm wide × 1.05mm thick. KYA also lists a wire diameter reference of 1.17# for the 4K Series.
The individual 410K, 413K, 416K and 419K specification table lists a chisel point.
Stainless steel is listed as a material option for the 4K Series. The current product description references Grade 304 stainless steel. Confirm available lengths, grade and packaging when ordering stainless steel staples.
The published galvanized SKU table lists 100 staples per stick and 5,000 staples per box, with 20 boxes per carton.
KYA publishes references including PREBENA E, ATRO 90, SENCO L, DUOFAST 1800, FASCO 90, HAUBOLD 6000, HOLZHER C, MAX 4MA, NIKEMA 90 and SPOTNAILS 48. Confirm the exact tool model and accepted fastener dimensions before purchase.
Typical applications include cabinetry, drawers, furniture components, casebacks, paneling, lattice, molding, decorative trim and upholstery where the selected staple dimensions are appropriate.
Galvanized staples provide corrosion protection compared with uncoated carbon steel, but suitability depends on moisture, chemicals, treated lumber and other exposure conditions. Confirm the required finish or stainless steel grade for demanding environments.
Do not select a replacement by nominal crown width alone. Compare gauge, actual crown dimension, wire width, wire thickness, leg length and stapler specifications before substituting one staple series for another.
KYA supplies 18 Gauge narrow crown staples for fastener distributors, wholesalers, furniture manufacturers, woodworking factories and professional industrial buyers. Send your required staple length, material, tool model, quantity and delivery destination for product confirmation and quotation.

KYA Fasteners states that it has more than 20 years of fastener manufacturing experience and serves customers in over 50 countries. The published company information describes SGS-certified production and lists shipment from Qingdao port within 20–30 days.

Custom lengths and galvanized high carbon steel or stainless steel options are listed for this product family. Share the required 4K item code and specifications to confirm availability.
Glue collation is specified for jam-free loading in compatible pneumatic staplers. Chisel points support clean penetration, while the narrow crown format is described as providing strong holding without splitting suitable materials. Actual feeding and joint performance depend on the stapler setup and substrate.
For suitable trim and woodworking joints, narrow crown staples are described as offering faster application and higher shear resistance than brad nails. Results depend on the substrate, fastening direction and installation setup; test the selected size in the intended material.
