Value Collection R63062882 4-40 X 1/4 in Flat Head Screw

Product Description

The VALUE COLLECTION R63062882 is a 4-40 x 1/4 inch flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. This screw uses Unified National Coarse (UNC) thread form and is sized for light-duty fastening applications common in electrical enclosures, control panels, instrumentation housings, and mechanical assemblies. The flat head profile sits flush with the mating surface when installed in a countersunk hole. Sold in a minimum quantity of 100 pieces per order, this screw is a standard stocking fastener for maintenance shops, contractors, and technicians who need reliable corrosion-resistant hardware at hand.

This screw is suited for residential and commercial trade applications where a small-diameter, corrosion-resistant fastener is required. Common installation scenarios include securing terminal strips, cover plates, and electronic components inside HVAC control boxes, electrical panels, and plumbing equipment enclosures. The 18-8 stainless steel construction resists oxidation in humid or mildly corrosive environments, making it appropriate for both indoor and light outdoor use. The slotted drive accepts a standard flat-blade screwdriver, a common tool in any trade kit.

Compatibility

Designed for use in any application requiring a 4-40 UNC threaded fastener with a flat head profile, including control panel assemblies, electrical enclosures, and light mechanical fixtures.

Installation Notes

Install using a flat-blade screwdriver sized to the slot width to avoid cam-out and slot damage. Ensure the receiving hole is properly countersunk to the correct angle to allow the flat head to sit fully flush. De-energize and lock out any electrical or mechanical equipment before installing or removing fasteners inside live enclosures. Do not overtighten into tapped plastic or thin sheet metal to prevent thread stripping.
