Product Description

By entering your model number, you can make sure that this fits.

Heavy gauge sheet metal, aluminum, cast iron, brass, and plastic are all suitable for thread cutting screws with type F points, which have machine screw threads that taper down to a blunt edge.

Steel is frequently used in applications that require a high level of strength.

Mild corrosion resistance and lubricity are provided by the black oxide finish.

The flat undercut head has a flat top and an 82-degree cone-shaped bearing surface. It is undercut for use in shallow countersunk holes.

The Phillips drive features an x-shaped slot that accepts a Phillips driver and is intended to prevent overtightening.

Commercial door frames will look great with this

5/5

I went to four different hardware stores in the area in search of a suitable screw for my fire station's commercial door frames but came up empty-handed. This screw was a perfect fit and fixed our problem with sagging hinges.

These fit perfectly into a steel door frame as a commercial door hinge

5/5

These are a perfect fit for a commercial door hinge into a steel door frame, and they have a 12/24 thread size and an undercut countersink. I haven't been able to locate them in any of the nearby big box stores. When I bought these, I wasn't sure if they were the right thread size, but I'm glad I did.

Screws are difficult to come by

5/5

Commercial grade door hinges require standard thread/length/undercut head screws, which are extremely difficult to come by for some reason. These are fantastic!.
