Value Collection 92686 Machine Screw 1/4-20 X 1/2 in Round Head

Product Description

The VALUE COLLECTION 92686 is a 1/4-20 x 1/2 inch round head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. It follows the Unified National Coarse (UNC) thread standard and is measured length-under-head. The 18-8 stainless steel construction provides solid corrosion resistance, making this fastener suitable for general mechanical assembly work in HVAC, plumbing, electrical panel, and equipment enclosure applications. Installation is straightforward with a standard flat-blade screwdriver. This fastener is sold in multiples of 25 units per order.

This screw is used in a wide range of light-duty mechanical and structural fastening tasks. Common applications include securing control boards, mounting brackets, access panels, equipment enclosures, and junction boxes. The round head profile sits above the material surface, making it a practical choice where a low-profile dome head is acceptable and countersinking is not required. Trade professionals in HVAC, electrical, and plumbing work regularly stock this size for field repairs and equipment assembly.

Installation Notes

Install with a flat-blade screwdriver sized to the slot. De-energize all electrical equipment and shut off system power before fastening or removing screws near live components. Follow applicable NEC or equipment manufacturer torque guidance for panel and enclosure hardware. Avoid cross-threading by starting the screw by hand before applying tool torque.
