Hillman Fasteners 47705 Roofing Screw 10x3 in Gray Box 12

Product Description

The HILLMAN FASTENERS 47705 is a 10x3 inch gray hex washer head roofing screw designed for self-piercing installation into metal sheeting and roofing panels. The ceramic coating provides corrosion resistance suited to exterior roofing applications. Each screw includes a neoprene washer that compresses at installation to create a weatherproof seal at the fastener point. This hardware is installed by roofing contractors, sheet metal workers, and commercial building tradespeople working with metal roofing and wall panel systems.

This screw is used in metal-over-metal and metal-over-substrate roofing assemblies where a self-piercing fastener eliminates the need to pre-drill. The hex washer head allows installation with a standard hex driver bit and drill or impact driver. The gray ceramic coating blends with common roofing panel colors. Sold in a box quantity of 12 screws, this SKU is suited for small repair jobs or supplemental stock. The neoprene washer provides a flexible seal that accommodates minor panel movement and thermal expansion.

Installation Notes

Installation is performed by qualified roofing or sheet metal contractors following applicable building codes. Power down any adjacent electrical systems before working on metal roofing assemblies. Use a hex driver bit sized to the fastener head and set clutch torque to avoid overdriving, which can compress the neoprene washer excessively and compromise the seal. Do not mix ceramic-coated fasteners with dissimilar metal panels without verifying galvanic compatibility.
