Würth #8 x 1" Washer Head Assembly Screw Combo Drive - Sharp Point Turbo Thread Lubricated, 3670000228961 500 - 500/Box

A Short, Sure-Seating Screw Built For Thin Stock And Hardware Backing

The Würth #8 x 1" washer head assembly screw is a lubricated, sharp-point fastener sized for applications where a longer screw would either over-penetrate or break through the back face of the panel. The turbo thread design drives fast, the broad washer head distributes clamping load without a countersink, and the combination drive accepts a #2 Phillips or a #2 square bit in the same recess.

Key Features

• Washer head provides a wide, flat bearing surface that pulls flush against the material face without requiring a countersink bore.
• Turbo thread reduces driving torque and speeds penetration in softwood, plywood, MDF, and particleboard.
• Sharp point self-starts in wood-based panels and sheet goods without a pilot hole in most applications.
• Combination Phillips and square drive recess accepts a #2 Phillips or a #2 square bit in the same head — use whichever bit is already in the driver.
• Lubricated finish further reduces installation torque, keeping driving smooth and consistent through a production run.
• 500 per jar with a 2" drive bit included in the package.

Where A 1-Inch Length Earns Its Place

At 1", this screw is sized for panels and assemblies where penetration depth matters as much as holding power. Attaching shelf hardware, drawer-slide mounting plates, and light-duty brackets to 3/4" sheet goods is a natural fit: the screw engages the full thickness of the panel without pushing through the show face. The same length works well for fastening back panels and cabinet bottoms into rabbeted grooves, and for securing drawer-guide blocks and other blocking pieces to cabinet interiors. Any time a 1-1/4" or longer screw would risk show-face blowout, this is the length to reach for.

Turbo Thread, Lubricated Finish, And A Drive That Works With What You Have

The turbo thread geometry is designed to bite quickly and reduce the resistance you feel through the driver during repeated fastening. Combined with the dry-lubricant coating on the screw body, driving stays consistent from the first screw in the jar to the last — useful on a production run where torque variation causes head strip-outs or inconsistent seating depth. The combination drive recess is the practical benefit of not having to match bit inventory to screw inventory: a #2 square bit holds the screw on a correctly sized bit for one-handed placement, and a #2 Phillips fits the same recess when that is what is loaded in the gun. The washer head is broad enough to bear cleanly against melamine, hardwood ply, and raw particleboard without the head cocking or dimpling the surface around the fastener.

The Right Screw For Cabinet Shops And Production Assembly

This screw suits cabinet shops running hardware installations and assembly operations at volume. The jar pack keeps the screw accessible on a bench or cart without the bulk of a full pail, and the included drive bit means the first jar on a new job does not require a separate bit order. Installers fitting out kitchen or bath cabinets on site will find the short 1" length particularly useful when mounting undermount hardware and light brackets in confined spaces where a longer screw is awkward or unsafe. The #8 gauge is the standard working size for this type of interior panel fastening, and the lubricated finish means the driver does not need to work hard even in denser plywood or hardwood-veneer ply.

Short Screw, Long Run

When the job calls for a 1" washer head screw that drives fast, seats clean, and works with the bits already on the truck, this Würth assembly screw covers the task — 500 at a time.
