FastCap #8 x 1-1/4" Flat Head Installation Screw Square Drive - Type 17 Auger Point Coarse Thread Zinc, PHZ8.1.25"-200 SQU - 200/Box

Installation Screw Sized For 3/4-Inch Stock Joinery

The FastCap #10 x 1-1/4 inch flat head installation screw is a coarse-thread wood screw built for cabinet assembly, casework, and general wood joinery where the combined stock thickness calls for a short, controlled fastener. The 1-1/4 inch length is a natural fit for single-layer 3/4-inch panels and hardware attachment into cabinet-grade material.

Key Features

• 1-1/4 inch length sized to work through single 3/4-inch stock without over-penetrating the mating panel.
• Flat head with underhead nibs mills its own countersink as the screw seats, keeping the head flush without a separate countersink step.
• Type 17 Auger point cuts into wood fibers quickly and clears chips at the tip to reduce driving torque and limit splitting.
• Coarse thread delivers strong pull-out resistance in solid wood, plywood, and cabinet-grade substrates.
• #2 square drive designed to hold the screw on a correctly sized bit for controlled one-handed placement.
• Zinc-plated carbon steel provides standard corrosion protection for dry interior applications.

Where This Length Makes Sense

At 1-1/4 inches, this screw is at home wherever the job calls for a fastener that penetrates deeply enough to grip without blowing through the back face of the receiving piece. Attaching cabinet backs to a 3/4-inch panel, securing hardware mounting blocks, and building interior cabinet components are all situations where a longer screw would over-penetrate and a shorter one would leave too little thread engagement. The coarse thread pattern holds well across solid woods, plywood, and furniture-grade sheet goods used in typical shop and installation work.

Head, Point, and Drive Working Together

The flat head carries underhead nibs that score the surrounding wood as the screw is driven home, milling a clean countersink on the fly. That keeps the head sitting flush in hardwoods, softwoods, and cabinet panels without requiring a separate countersink operation on every hole. The Type 17 Auger point adds a fluted cutting edge at the tip that clears material quickly and reduces the force needed to start and drive the screw, especially useful in denser hardwoods and engineered sheet goods. The #2 square recess is designed to hold the screw on a correctly sized bit, which helps with placement in tight cabinet interiors where two-handed positioning is awkward.

Who Reaches For This Screw

Cabinet shops building face-frame and frameless carcasses, installers fitting cabinet components on site, and finish carpenters working with 3/4-inch material all find a regular use for a screw in this length. The 200-piece box keeps a working supply on hand without occupying excess storage space, making it a practical choice for installers who carry a focused fastener kit rather than bulk pails. The zinc finish suits the controlled indoor environments where most cabinetry and finish carpentry work happens.
