Value Collection 5012MSF Flat Head Machine Screw 1/2-13

Product Description

The VALUE COLLECTION 5012MSF is a flat head slotted machine screw designed for general fastening applications in metal, wood, and composite assemblies. It features a 1/2-13 unified coarse thread and an overall length of 3/4 inches, making it suited for moderate-depth fastening where a flush or countersunk finish is required. Manufactured from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 standards. It is installed with a standard flat-blade screwdriver and is appropriate for maintenance, fabrication, and repair work across mechanical, HVAC, electrical, and plumbing trade applications.

This screw is commonly used in light to medium-duty fastening situations where a countersunk seat is needed and a low-profile head is required at the surface. The coarse 1/2-13 thread engages quickly and holds reliably in tapped holes in steel brackets, panels, junction boxes, and similar hardware. Trade professionals will find it useful for securing covers, mounting components, and general mechanical assembly in both residential and commercial settings. This item is sold in a minimum order quantity of 5 pieces.

Compatibility

Designed as a standard 1/2-13 UNC flat head machine screw suitable for use in any tapped or threaded hole conforming to 1/2-13 unified coarse thread specifications.

Installation Notes

Install using a flat-blade screwdriver or slotted bit matched to the head recess. Ensure the mating hole is properly tapped to 1/2-13 UNC before installation. De-energize and lock out any electrical or mechanical equipment before fastening components in live systems. Do not overtighten into soft or thin materials, as the flat head may pull through without a backing washer.
