Value Collection 1208MSL 12-24x1/2 Fillister Slotted Machine Screw

Product Description

The VALUE COLLECTION 1208MSL is a 12-24 unified coarse thread machine screw with a fillister head and slotted drive, manufactured from steel with a zinc finish. The fillister head profile features a small diameter and tall, straight sides, making it well suited for counterbored holes and close-clearance assemblies where a raised head is acceptable. The 0.5-inch length is measured under the head per ASME B18.6.3 and SAE J82. This fastener is used in general mechanical assembly and maintenance applications and is handled by millwrights, HVAC technicians, electricians, and maintenance mechanics.

This screw is used in light-duty metal fastening applications across residential and commercial equipment. Common install scenarios include securing electrical panels, junction boxes, HVAC access covers, motor mounting plates, and similar sheet metal or light structural assemblies where a 12-24 thread form is specified. The zinc finish provides basic corrosion resistance for indoor and sheltered environments. Sold as a single package with a minimum order quantity of 100 pieces.

Installation Notes

Power down or de-energize any equipment before replacing fasteners on electrical enclosures or control panels. Use a flat-blade screwdriver or bit sized to fit the slot fully to avoid cam-out and head damage. Verify the mating tapped hole is clean and undamaged before installation.
