Value Collection 1224MSL Fillister Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 1224MSL is a 12-24 threaded machine screw with a fillister head and slotted drive, designed for general-purpose mechanical fastening in industrial, electrical, and trade applications. The screw measures 1.5 inches in length under the head and is manufactured from steel with a zinc finish for basic corrosion resistance. Built to ASME B18.6.3 and SAE J82 standards, this fastener delivers consistent dimensional tolerances suited to production and maintenance environments. Electricians, plumbers, HVAC technicians, and general contractors reach for this screw when assembling panels, junction boxes, fixtures, and equipment enclosures where a low-profile fillister head is required.

This machine screw fits applications where a slotted fillister head is preferred over pan or flat head styles, providing a deeper slot for higher driver torque and a raised edge that helps retain the screwdriver. It is well suited for use in metal panels, thin sheet assemblies, and enclosures common in light commercial and residential electrical and mechanical work. Sold in minimum quantities of 100 per order, this screw is practical for contractors and facilities maintenance crews who need reliable stock on hand.

Key Features

• 12-24 unified coarse thread for broad compatibility with standard tapped holes
• Fillister head profile provides a deep slotted recess for positive driver engagement
• 1.5-inch length under head suits moderate-depth fastening in metal and composite assemblies
• Steel construction with zinc finish offers basic corrosion resistance for indoor applications
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards
• Sold in multiples of 100, suitable for production and maintenance stocking

Compatibility

Designed as a standard 12-24 machine screw for use in any application requiring a fillister head, slotted drive fastener conforming to ASME B18.6.3 and SAE J82 specifications in inch measurement.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slot without slipping, which reduces the risk of stripping the head. Ensure the mating tapped hole or nut is clean and free of debris before driving. For electrical enclosure applications, follow NEC requirements for fastener use in listed assemblies. Do not over-torque steel machine screws in thin sheet metal, as thread stripping can occur without a proper nut or insert.
