Value Collection 1212MST Machine Screw 12-24 Truss Head

Product Description

The VALUE COLLECTION 1212MST is a 12-24 unified coarse thread machine screw designed for general mechanical fastening in metal assemblies. The truss head profile offers a wider, low-profile bearing surface compared to a standard pan head, distributing clamping load across a larger area. The slotted drive accepts a standard flat-blade screwdriver. Constructed from steel with a zinc finish, this screw meets ASME B18.6.3 and SAE J82 dimensional and material standards. Length under head is 0.75 inches. Sold individually per piece, with a minimum order quantity of 100 units.

This screw is suited for light- to medium-duty fastening applications in HVAC equipment panels, electrical enclosures, plumbing fixtures, and general sheet metal or machined component assembly. The zinc finish provides basic corrosion resistance for indoor and light-duty exposed applications. Technicians and assemblers reach for this size when joining thin metal panels or attaching components to tapped holes in equipment housings.

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 12-24 threaded fastener with a truss head profile and slotted drive.

Installation Notes

Installation is performed by hand tools or a flat-blade screwdriver; power drivers should be set to a controlled torque to avoid stripping the slotted drive or over-driving into thin material. Ensure the receiving hole is properly tapped to 12-24 before installation. De-energize any electrical equipment before fastening panels or enclosures. Follow applicable equipment manufacturer guidelines for fastener torque on specific assemblies.
