Value Collection 1240MSF 12-24 X 2.5 in Flat Head Slotted Screw

Product Description

The VALUE COLLECTION 1240MSF is a 12-24 unified coarse thread machine screw with a flat head and slotted drive, manufactured from steel with a zinc finish. At 2.5 inches overall length, this fastener meets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency. The flat head profile sits flush with or below the mating surface when countersunk, making it a practical choice for panel assemblies, brackets, and enclosures where a flush finish is required. Sold individually with a minimum order quantity of 100 units, this screw suits production runs, MRO restocking, and field service applications across HVAC, electrical, and general mechanical trades.

This machine screw is suited for use in light to medium-duty fastening applications in both residential and commercial settings. Common install scenarios include securing control panels, junction box covers, equipment enclosures, and structural brackets where a countersunk flat head profile is specified. The 12-24 thread size is a widely used coarse-thread designation compatible with standard 12-24 tapped holes and nuts. The zinc finish provides basic corrosion resistance suitable for indoor and sheltered environments.

Installation Notes

A licensed electrician, HVAC technician, or qualified mechanical tradesperson should de-energize and lock out equipment before servicing any fastened assembly. A standard flat-head screwdriver or slotted bit sized for a No. 12 fastener is required for installation. The mating material must be pre-tapped or fitted with a threaded insert to the 12-24 specification — do not self-tap with this fastener. Torque to the specification called out in the equipment manufacturer's documentation.
