Würth #8 x 1-1/2" Flat Head Assembly Screw Square Drive - Type 17 Auger Point Coarse Thread Black, 3670000353961 5000 - 5000/Box

Right-Length Reach for 3/4-Inch Stock and Thin-Panel Joinery

The Würth #8 x 1-1/2 inch flat head assembly screw is a coarse-thread fastener built for cabinet carcass work, drawer boxes, and panel joinery where a 1-1/2 inch screw hits the right depth without over-penetrating the material. It carries a Type 17 Auger point, milling nibs under the flat head, a #2 square drive, and a black finish — packed 5,000 to the pail for production-volume use.

Key Features

• Type 17 Auger point cuts a flute at the tip to clear chips and reduce splitting as the screw enters wood or panel material.
• Milling nibs under the flat head cut their own countersink as the screw seats, leaving a flush, clean surface without a separate countersink step.
• #2 square drive provides solid bit engagement with low cam-out risk during repetitive driving.
• Coarse thread sized for wood, plywood, MDF, particleboard, and melamine-faced panels.
• Black finish blends with dark cabinet interiors and finished panel surfaces where a neutral head color matters.
• 5,000-count pail supports continuous shop production without frequent restocking interruptions.

Where 1-1/2 Inches Does the Right Work

At 1-1/2 inches, this screw is sized for the most common joints in cabinet and furniture production: face panels joining edge material, drawer box sides meeting bottoms or backs, and carcass assembly where two layers of 3/4-inch sheet goods come together. The length gives adequate thread engagement without punching through the far face of a single panel. For shops building frameless boxes or assembling drawer components at volume, this length handles a wide range of standard joints without reaching for a different screw mid-run.

Point, Head, and Drive Working Together

The Type 17 Auger point uses an extended flute to remove material at the tip rather than compress it, which keeps splitting risk low in denser panels and hardwood-faced components. As the screw finishes its drive, the milling nibs under the flat head cut a clean countersink directly into the substrate, so the head sits flush without a pre-countersinking step. The #2 square drive holds the bit securely in the recess with a correctly sized bit, which matters when driving volume across a production run where cam-out would slow the work and damage heads. The black finish is not a corrosion-protection coating — this screw is for dry interior assembly, where the color serves appearance rather than exposure resistance.

Built for Production Cabinet and Panel Assembly

This screw fits cabinet shops, millwork operations, and woodworking production environments where consistent, high-volume fastening in engineered panels is the daily work. The 5,000-count pail keeps a practical supply on hand for production lines without constant reordering. Pail packaging is convenient for movement around the shop or to the job site. It is a strong fit for assembling frameless cabinet boxes, joining melamine-faced carcass parts, building drawer boxes, and fastening panel-to-panel connections in MDF or particleboard. For softwood framing, structural connections, or any exterior application, a different screw is the right call — this one belongs in the indoor panel and cabinet shop.

A Production-Volume Screw Sized for the Job at Hand

When the joint calls for a 1-1/2 inch flat head screw and the shop runs high volume, this Würth assembly screw delivers consistent point performance, clean head seating, and a square drive that holds up through a full production day — all from a 5,000-count pail that keeps the line moving.
