Hillman Fasteners 90407 Machine Screw 1/4-20 X 2 in 100PK

Product Description

The HILLMAN FASTENERS 90407 is a 1/4-20 x 2-inch slotted round head machine screw with a zinc plated finish, sold in a 100-pack. The 1/4-20 thread pattern is a standard unified coarse thread, and the 2-inch length suits a wide range of medium-depth fastening applications. The zinc plating provides basic corrosion resistance for general indoor and light-duty outdoor use. These screws are driven with a standard flathead screwdriver and are a practical bulk option for trade professionals stocking hardware for panels, equipment enclosures, brackets, and mechanical assemblies.

This machine screw is suited for use in HVAC equipment assembly, electrical panel work, plumbing fixture mounting, and general mechanical fastening where a 1/4-20 coarse thread is specified. The round head profile sits above the mating surface and distributes clamping load across a wider area than a flat or pan head. The 100-pack quantity supports job-site or shop use where multiple fasteners of the same size are routinely needed.

Key Features

• 1/4-20 unified coarse thread for broad hardware compatibility
• 2-inch length suitable for medium-depth fastening applications
• Zinc plated finish for basic corrosion resistance
• Slotted round head driven with a standard flathead screwdriver
• 100-pack quantity reduces reordering frequency on active jobs

Compatibility

Designed as a standard 1/4-20 coarse thread machine screw for use wherever that thread size and a slotted round head profile are specified in mechanical, electrical, or HVAC assemblies.

Installation Notes

Installation requires a flathead screwdriver or bit sized to the slotted head. Always match the screw length to the material stack being fastened to avoid bottoming out or insufficient thread engagement. Power down any electrical equipment before fastening hardware to live panels or enclosures. Follow applicable NEC or equipment manufacturer guidelines when securing components inside electrical or control enclosures.
