Value Collection GRDG3500075OP-75PK Deck Screw 3.5 in 75PK

Product Description

The VALUE COLLECTION GRDG3500075OP-75PK is a Number 12 bugle head, square drive steel deck screw with an overall length of 3.5 inches. This fastener is designed for structural wood-to-wood connections in deck framing, decking boards, and general exterior wood construction. The bugle head profile countersinks smoothly into wood without splitting the surface fiber, while the square drive recess reduces cam-out during high-torque installation. Each package contains 75 screws, making this suitable for both spot repairs and larger project runs. Installed by carpenters, general contractors, and experienced DIYers working on residential or light commercial wood structures.

This screw is used in outdoor decking applications including pressure-treated lumber assemblies, deck boards, stair stringers, and substructure framing. The 3.5-inch length provides adequate penetration depth for standard 5/4 decking boards into dimensional lumber joists. The steel construction is suited for dry and treated-lumber environments where a corrosion-resistant coating may be applied separately. This package quantity of 75 is appropriate for small-to-medium deck repairs or section installations.

Installation Notes

Installed by carpenters or qualified contractors using a square-bit driver or impact driver rated for the fastener size. Pre-drilling is recommended when working near board ends to prevent splitting, particularly in hardwood decking stock. Follow applicable building codes for fastener spacing and penetration depth when constructing load-bearing deck structures. Inspect lumber for moisture content and treat as required before fastening to extend service life.
