SENCO #8 Wood Screws 4000 Pack
SENCO #8 x 1-3/4 in wood screws come in a 4000-piece bulk pack for high-volume wood-to-wood fastening. The steel fasteners feature a zinc yellow finish and a flat head with a #2 square drive. Type 17 points and coarse threads start quickly in timber without pre-drilling.
Capacity and Headroom for Framing Work
The 4000-count box supports extended framing, decking or subfloor jobs without frequent reorders. Each screw measures 1 39/64 in long with a 0.32 in head width and 0.18 in head height for consistent countersinking. Coarse threads hold well in softwood but can strip in dense hardwoods.
Upgrade from Small Packs or Phillips Drive
Moving from small boxes or Phillips-head screws cuts downtime and reduces cam-out on the job site. The square drive transmits torque cleanly while the Type 17 point speeds penetration in dimensional lumber. Buyers who need corrosion resistance beyond ASTM B117 salt spray performance should select a different coating.

Questions about this item
Will the #8 x 1-3/4 in coarse threads hold in the same studs I used for #6 screws?
The #8 diameter and coarse threads are designed for wood-to-wood applications and will engage securely in studs that previously accepted smaller fasteners.
How do I confirm the Type 17 point is starting correctly without splitting the board?
The Type 17 point reduces splitting; you will feel the screw bite immediately and the flat head will sit flush when driven with a #2 square bit.
Does the 4000 pack include the #2 square drive bit or must I buy it separately?
The pack contains only the steel zinc-yellow screws; a #2 square drive bit is not included and must be purchased separately.
