6 x 1/2 in. Undercut Flat Head Mounting, Zinc, Phillips - Qty:25

6 x 1/2 in. Undercut Flat Head Mounting Screws – 25 Count

These 6 x 1/2 in. Undercut Flat Head Mounting Screws are designed for precise installation of drawer slides and cabinet hardware, especially applications with thin-gauge mounting holes and limited clearance beneath the screw head. The undercut flat head features a reduced bearing surface that allows the screw to seat properly in compatible mounting holes where a conventional flat head may not fit correctly.

Ideal for cabinetmaking, furniture assembly, and woodworking projects, these mounting screws are particularly useful for installing drawer slides with small or countersunk mounting holes. Their compact head design helps provide a clean, secure fit while accommodating the mounting requirements of compatible drawer slide hardware.

Undercut Flat Head Design

Unlike a standard flat head screw, an undercut flat head has a recessed underside that reduces the bearing surface beneath the head. This design is especially useful when fastening thin metal components, drawer slides, and other hardware with limited space around the mounting hole.

The reduced head profile helps the screw seat correctly in compatible mounting holes without interfering with nearby slide components. Proper alignment is important during installation, as forcing a screw into an angled or misaligned hole can damage the drive recess or prevent the head from seating properly.

Ideal for Drawer Slides and Cabinet Hardware

These 6 x 1/2 in. mounting screws are well suited for drawer slide installation and other hardware applications requiring a compact undercut head. They are particularly useful for compatible Grass drawer slides and other slides with smaller mounting holes.

Whether you are installing new cabinet drawers, replacing existing mounting screws, or assembling furniture, these screws provide a practical fastening solution for applications where standard flat head screws may not seat properly.

Clear Zinc Plating and RoHS Compliance

The clear zinc finish provides a clean, silver appearance that complements many cabinet hardware and metal mounting components. Electroplated zinc offers moderate protection against rust and corrosion, making these screws suitable for many indoor woodworking, cabinetry, and furniture applications.

All of our zinc-plated and yellow zinc-plated products use trivalent zinc, making these screws RoHS-compliant. For best results, use them in appropriate interior applications and avoid prolonged exposure to moisture or corrosive environments.

Recommended Installation Tips

Accurate alignment is essential when installing drawer slides. A self-centering drill bit helps position the pilot hole in the center of the mounting hole, reducing the chance of misalignment. For applications requiring precise pilot-hole placement, our #MS-5107 self-centering drill bit with a 7/64 in. drill is recommended.

Keep the screw straight during installation and use controlled driving pressure to help the undercut head seat correctly. Avoid overtightening, excessive side loading, or forcing the screw into a misaligned hole, as these conditions can damage the drive recess or compromise proper seating.

A Practical Fastening Solution for Cabinetmakers

Choose these 6 x 1/2 in. Undercut Flat Head Mounting Screws for drawer slide installation, cabinet hardware assembly, and woodworking projects that require a compact head profile. With a clear zinc finish, #2 Phillips drive, and convenient 25-count packaging, they are a useful addition to any cabinetmaker's or woodworker's fastener inventory.

When installing undercut screws, use care to keep the screw straight and avoid excessive driving force. Proper alignment helps the screw seat correctly and reduces the possibility of damaging the undercut head.
