FastCap #8 x 2-1/2" Flat Head Installation Screw Square Drive - Type 17 Auger Point Coarse Thread Zinc, PHZ8.2.5"-150 SQUAR - 150/Box

Extra Reach And A Clean Seat For Thicker Stock

The Fastcap #10 x 2-1/2-inch flat head installation screw is built for jobs where a shorter screw will not reach. With a coarse thread, Type 17 Auger point, nibs under the flat head, and a #2 square drive, it drives cleanly through thicker assemblies and seats flush without a separate countersink step.

Key Features

• 2-1/2-inch length gives enough thread engagement for thicker panels, built-up assemblies, and deeper cabinet joinery.
• Type 17 Auger point clears wood fibers at the tip to reduce splitting and lower the torque needed to drive the screw home.
• Flat head with milling nibs mills its own countersink as the head seats, leaving a flush surface without pre-drilling a countersink.
• #2 square drive is designed to hold the screw on a correctly sized bit for more controlled placement in tight spots.
• Coarse thread on a #10 shank pulls the joint together firmly in solid wood and typical cabinet materials.
• Zinc finish on carbon steel for dry, indoor cabinet and woodworking applications.

Where The 2-1/2-Inch Length Earns Its Keep

At 2-1/2 inches, this screw reaches through face frames into solid cabinet boxes, through doubled panels, and into blocking or nailers that sit behind a finished surface. It is the right length when you need thread engagement well past the first layer of material. Typical scenarios include attaching cabinet assemblies to wall blocking, through-fastening stacked sheet goods, or securing hardware backing that demands a longer grip. The coarse thread on a #10 shank provides solid pull-out resistance in solid pine, poplar, plywood, and MDF.

Flat Head, Nibs, And A Clean Finish

The flat head is designed to sit flush with the surface after driving. The milling nibs on the underside of the head relieve wood fibers as the screw seats, helping the head countersink cleanly into the material without tearing the surface. This is especially useful when driving into finished or painted wood where a separate countersink drill step would add time. The zinc finish on the carbon steel body is suited to dry indoor work.

Who Reaches For This Screw

Cabinet installers who are through-fastening into wall structures, shop crews assembling thicker carcass panels, and finish carpenters who need a longer installation screw with a flush head will all find this length useful. The 150-screw box suits a project or a focused run on the assembly bench without the overhead of a large bulk pack. The #2 square drive works with the bits most production shops already have in rotation.

Questions About This Screw

The Right Screw When Depth Matters

When the job calls for a flat head installation screw that reaches through thicker stock, seats flush on its own, and drives with a standard #2 square bit, the Fastcap #10 x 2-1/2-inch is the size to have on the bench.
