Value Collection C57500311 Machine Screw 10-32 Flat Head

Product Description

The VALUE COLLECTION C57500311 is a 10-32 x 0.5 inch flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. The unified fine thread (UNF) pitch and countersunk flat head profile make this screw a standard choice for flush-mount fastening in sheet metal, electrical enclosures, HVAC equipment panels, and light mechanical assemblies. The 18-8 stainless alloy provides solid corrosion resistance for indoor and mildly wet environments. This screw is sold in a minimum order quantity of 50 pieces per purchase, with one piece per package unit as counted in the supplier system.

This fastener is used across a wide range of trade and light industrial applications wherever a 10-32 UNF thread is called out. Common use cases include securing control board brackets, panel covers, electrical junction box covers, and equipment access panels in HVAC, electrical, and plumbing service work. The flat head seats flush with the mating surface when used with a properly countersunk or pre-tapped hole, keeping clearances tight in compact assemblies. Installers in maintenance, equipment repair, and original equipment manufacturing rely on this size as a standard stock item.

Installation Notes

Installation requires a properly tapped or pre-threaded 10-32 UNF hole or mating nut. Use a flat-blade screwdriver matched to the slot width to avoid cam-out and head damage. For flush seating, the receiving material should be countersunk to the flat head angle. Power down and de-energize any electrical or HVAC equipment before fastening or removing panel hardware per standard lockout/tagout procedures.
