The featured roofing nail combines a full round head, smooth shank and diamond point. Each element serves a different function in the fastening system.
The broad roofing head provides bearing area against the roofing material. The smooth shank is a standard configuration for general roofing applications, while the diamond point is designed to enter compatible wood substrates efficiently.



KYA supplies .120" diameter coil roofing nails in multiple lengths. Choose the nail length according to the roofing material, deck thickness, number of layers and required penetration.

Size, shank and finish combinations can vary within the roofing nail range. Confirm the exact specification and packing configuration when requesting a quotation.
ASTM F1667 includes a 7/8" × .120" power-driven roofing nail size among its dimensional classifications for driven fasteners.
When ASTM F1667 compliance is required by a purchase specification, construction document or roofing system, confirm the applicable documentation for the exact KYA fastener supplied. Nominal dimensions alone should not be used as proof of complete product compliance.
Asphalt shingles: installations where a 7/8" roofing nail meets the roofing manufacturer's required penetration and deck conditions.
Fiberglass shingles: compatible roof-covering applications using full-round-head roofing nails.
Roofing felt: fastening where this nail length and head configuration are appropriate.
Underlayment: applications where wire-collated roofing nails are specified by the installation method.
Insulation board: compatible fastening applications using broad-head roofing nails.
The 7/8" length should not be assumed suitable for every roof assembly. Required fastener length depends on shingle thickness, underlayment, roof deck, number of layers and the minimum penetration specified by the roofing manufacturer or local project requirements.
The featured nail uses an electro-galvanized zinc coating to provide corrosion protection for roofing applications where this finish is permitted.
Electro-galvanized roofing nails should not automatically be used in every exterior environment. For cedar, redwood, treated lumber, severe moisture exposure or corrosive environments, confirm the required fastener material and coating with the roofing or building-material manufacturer.
KYA lists additional configurations within its roofing nail range, including ring shank, hot-dip galvanized and stainless steel options. These should be selected according to the specific installation requirements.
| Option | Selection Consideration |
|---|---|
| Smooth Shank | Standard roofing configuration where smooth-shank nails meet the installation specification. |
| Ring Shank | Provides additional mechanical engagement with compatible wood substrates when increased withdrawal resistance is specified. |
| Hot-Dip Galvanized | Higher-level galvanized protection for applications where this coating is required. |
| 304 Stainless Steel | Corrosion-resistant option for applications requiring stainless steel fasteners. |
| 316 Stainless Steel | Available in selected configurations for more demanding corrosive environments when specified. |
The featured 7/8" × .120" wire-collated roofing nail falls within the published fastener ranges of several professional coil roofing nailers.
| Roofing Nailer | Published Fastener Range |
|---|---|
| Bostitch RN46 | Commonly listed for 15° .120" wire-collated roofing nails, including the 7/8" size. |

Tool compatibility should be confirmed using nail length, shank diameter, head diameter, collation material and coil configuration. Do not assume that every tool described as a 15° coil nailer accepts roofing nails of this specification.
A standard commercial packing configuration for this roofing nail format is approximately 120 nails per coil and 60 coils per box, giving approximately 7,200 nails per box.
The 7,200 figure refers to the box quantity, not the quantity in one coil. Confirm final packaging with KYA because carton and pallet configurations may vary by order and destination.
For distributor and bulk inquiries, provide the required nail length, shank type, finish or material, quantity, destination market, roofing application and pneumatic nailer model. If a project requires a particular fastener standard or corrosion-resistance level, include that requirement with the inquiry.
KYA's current product information lists a minimum order quantity of 100 coils and indicates that samples can be arranged. Confirm the current sample quantity, courier terms, production packing and MOQ when requesting pricing.
