Value Collection 92589 Machine Screw 1/4-20 X 1 in Flat Head

Product Description

The VALUE COLLECTION 92589 is a 1/4-20 x 1 inch flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. It uses Unified National Coarse (UNC) threading and is sold in a minimum order quantity of 25 pieces per package. The flat head profile sits flush with the mating surface when fully driven, making it a common choice in assemblies where a smooth, low-profile finish is required. Installers use a standard flat-blade screwdriver or slotted bit for installation. This fastener is suited for light mechanical and structural fastening tasks across a wide range of trade and industrial applications.

This screw is used in residential, commercial, and light industrial settings wherever a 1/4-20 UNC thread is specified. The 18-8 stainless steel construction provides good corrosion resistance, making it appropriate for indoor applications with moderate moisture exposure and for general-purpose assembly work. Electricians, plumbers, HVAC technicians, and general contractors commonly use 1/4-20 flat head machine screws for panel mounting, equipment assembly, and fixture attachment. The overall length is 1 inch, and the length under the head is also 1 inch, consistent with flat head geometry.

Compatibility

Designed as a standard 1/4-20 UNC flat head slotted machine screw for use in any application requiring that thread size and head style. Compatible with standard 1/4-20 tapped holes, threaded inserts, and hex nuts across inch-measurement fastener systems.

Installation Notes

Installation requires a flat-blade screwdriver or slotted bit sized to the head. Ensure the mating hole is properly tapped to 1/4-20 UNC before driving the screw to avoid cross-threading. For flush seating, a countersunk hole matching the flat head angle is required. Do not exceed the rated torque for the material being fastened, and verify thread engagement depth is sufficient for the application load.
