Value Collection 0512MSL 5-40 X 3/4 in Fillister Slotted Machine Screw

Product Description

The VALUE COLLECTION 0512MSL is a fillister head machine screw intended for precision fastening applications in mechanical assemblies, enclosures, and equipment panels. It features a 5-40 unified coarse thread and measures 3/4 inch in length under head. The fillister head profile offers a taller, narrower head than a standard pan head, providing a deeper slot for a more positive slotted driver engagement and a smaller footprint on the mating surface. Finished in zinc for basic corrosion resistance, this screw is manufactured from steel to ASME B18.6.3 and SAE J82 standards. It is installed by maintenance technicians, machine builders, and electricians working on enclosures, switchgear, and light mechanical assemblies.

This screw is suited for use in residential and commercial equipment panels, electrical enclosures, HVAC control boards, and general mechanical assemblies where a small-diameter, fine-tolerance fastener is required. The 5-40 thread designation is common in instrument panels, junction boxes, and light-duty metal-to-metal fastening. The zinc finish provides a degree of protection against oxidation in indoor or sheltered environments. This SKU is sold as a single package with a minimum order quantity of 100 pieces.

Key Features

• 5-40 unified coarse thread for reliable engagement in tapped holes
• 3/4 inch length under head for consistent, measurable clamp depth
• Fillister head profile provides deeper drive slot and reduced bearing surface footprint
• Slotted drive compatible with flat-blade screwdrivers and slotted power bits
• Zinc finish offers basic indoor corrosion resistance
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 5-40 tapped hole. Confirm thread engagement depth and hole preparation against ASME B18.6.3 tolerances before installation.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver or slotted bit driver. Ensure the receiving hole is tapped to 5-40 specifications before driving. Do not overtighten small-diameter machine screws, as this can strip the thread or shear the fastener. Follow applicable assembly or electrical enclosure standards such as NEC requirements when used in electrical panel applications.
