The Würth #8 x 1-inch washer head assembly screw is a short, production-ready fastener built for cabinet interiors, panel joinery, and hardware backing where you need a clean-seating head and reliable holding power without over-penetrating thin material. The combination drive, lubricated finish, and turbo thread keep the screw moving fast from the first placement to the last.
At 1 inch, this screw is matched to shallow fastening tasks that longer screws can't serve cleanly. Attaching a 1/4-inch or 3/8-inch cabinet back to a 3/4-inch panel, securing hardware backing strips, or fastening thin interior shelf cleats are exactly the situations where a longer screw would punch through the face or pull the joint apart. The 1-inch length keeps all the thread inside the stock where it belongs. It also works for drawer bottom attachment in production cabinet boxes, where consistent depth and a clean-sitting washer head matter across every unit on the line.
The combination drive recess accepts a #2 Phillips or a #2 square bit. A correctly sized bit allows the square recess to hold the screw for one-handed placement, which helps in tight cabinet interiors where getting two hands on a fastener isn't easy. The washer head's underside nibs mill a clean seat as the screw is driven, so the head sits flat on laminates and panel faces without tearing the surface. The lubricated finish reduces driving resistance, which is especially useful in high-density substrates like melamine-faced particleboard or MDF, where unlubricated screws can build heat and stall mid-drive.
This screw is designed for cabinet manufacturers, millwork shops, and finish carpenters who run through fasteners by the box. The turbo thread pattern drives fast, the combination drive accommodates whatever bit is in the gun, and the lubricated coating keeps the pace up across hundreds of identical joints. The 1-inch length is especially useful on assembly stations dedicated to cabinet backs, interior panel dividers, and hardware mounting. Contractors and remodelers who install pre-built cabinet boxes will also find the washer head's broad bearing surface useful on softer cabinet materials where a smaller head would pull through under load.
Yes. The 1-inch length is well suited for fastening a 1/4-inch or 3/8-inch back panel into a 3/4-inch cabinet side or rail, with full thread engagement in the substrate and no risk of punch-through.
The lubrication is a dry-to-the-touch coating applied to reduce driving friction. It is not a wet oil finish and does not interfere with standard wood glue joints or interior cabinet finishes.
The washer head has a wider, lower-profile flange than a standard pan head, spreading the clamping load over more surface area. The underside nibs mill a clean seat as the head lands, which helps it sit flat on laminate and panel faces without tearing the surface.
In most production cabinet materials, including melamine-faced particleboard and MDF, the sharp point will self-start without a pilot hole. For fastening very close to a panel edge, a pilot hole reduces the risk of surface fracture.
The drive recess accepts both a #2 Phillips and a #2 square bit in the same opening. Use the driver type that gives you the best bit engagement with the tools you have on hand.
When the joint is shallow and the surface finish matters, the 1-inch Würth washer head assembly screw delivers a clean seat, fast drive, and dependable hold without over-penetrating the stock.
