The Würth #8 x 1" Flat Head Assembly Screw is a coarse-thread cabinet fastener with a 30° sharp point, under-head nibs, and an AW20 drive. It is designed for fast, clean fastening in wood panels, cabinet carcasses, and furniture components where a flush-seated head and consistent bit engagement matter.
At 1" in length, this screw is sized for joining panels and components where penetration depth is limited, such as attaching cabinet backs, fastening interior dividers, or securing hardware blocking inside a cabinet carcass. The coarse thread grips solidly in solid wood and plywood. The 30° sharp point self-starts cleanly in most wood panel materials, and the flat head with nibs seats flush without a pre-drilled countersink in many applications. For shops running continuous assembly, having a screw that starts fast, drives cleanly, and seats level saves time across every cabinet in the run.
The zinc plating on this screw provides reliable corrosion protection for dry, climate-controlled interior environments. It is the appropriate finish for cabinet shop production, millwork assembly, and interior furniture manufacturing. This screw is intended for indoor work. For applications with moisture exposure or treated lumber, a corrosion-rated finish would be the right call instead.
Production cabinet shops are the primary audience for a box of 1,000 in this size. A 1" #8 coarse-thread assembly screw covers a range of interior joinery tasks, from panel-to-panel connections to hardware backing attachment, and the AW20 drive keeps bit changes minimal across those jobs. Finish carpenters and millwork installers working with pre-built cabinet components will also find this length useful where a longer screw would risk breaking through the opposite face. The flat head and nibs make it a good fit anywhere a flush, clean countersink matters without adding a separate countersink step to the workflow.
This screw uses an AW20 drive. The AW drive is a Würth proprietary system, so an AW20 bit is required for correct fit and torque transfer. Standard Torx or hex bits are not designed for this recess and should not be substituted.
The nibs are small milling ridges on the underside of the flat head. As the screw is driven, they cut a clean countersink in the wood so the head sits flush without a separate countersink operation. They are especially useful in hardwoods and laminates where a clean flush seat matters for the finished appearance.
In most softwood and plywood panel applications, the 30° sharp point self-starts without a pilot hole. In very dense hardwoods or when fastening close to an edge, a pilot hole helps prevent splitting and improves accuracy.
No. The zinc finish is rated for dry indoor environments. For exterior use or contact with pressure-treated lumber, choose a screw with a corrosion-rated coating such as hot-dip galvanized or a multi-layer exterior finish.
Coarse thread performs best in solid wood, construction plywood, and softwood panels, where the wider thread pitch grips wood fibers effectively and provides strong pull-out resistance. For MDF or particleboard, a chipboard-thread screw typically delivers better holding power.
This Würth #8 x 1" assembly screw is a reliable, no-friction choice for interior cabinet and panel joinery: sharp point for fast starts, nibs for flush seating, AW20 drive for clean torque transfer, and a box count that keeps the job moving without frequent restocking.
