Value Collection 0805MST 8-32 Truss Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0805MST is a truss head, slotted-drive machine screw designed for general-purpose fastening in metal assemblies, panels, and enclosures. It carries an 8-32 thread size with a 5/16-inch length under the head, making it well suited for thin-material applications where a low-profile, wide-bearing head is needed to distribute clamp load across the surface. Manufactured from steel with a zinc finish, the 0805MST meets ASME B18.6.3 and SAE J82 standards, confirming dimensional and mechanical conformance. A slotted drive accepts a standard flat-blade screwdriver. This screw is used by electricians, HVAC technicians, and general trade professionals wherever a compact, corrosion-resistant fastener is required.

This fastener is commonly used in light-gauge sheet metal work, electrical enclosures, junction boxes, HVAC equipment panels, and similar applications where a 8-32 thread pitch is specified. The truss head profile seats flush on flat and slightly curved surfaces without the use of a washer. It is sold in multiples of 100 pieces, making it practical for bench stock or field kit restocking. No washer is included or required by the design.

• Steel construction with zinc finish for corrosion resistance in light-duty applications
• Meets ASME B18.6.3 and SAE J82 dimensional and mechanical standards
• Material grade J82 confirms minimum mechanical property compliance

Compatibility

Designed as a general-purpose 8-32 machine screw for use in electrical enclosures, HVAC equipment panels, and light-gauge sheet metal assemblies requiring a truss head, slotted-drive fastener without a washer.

Installation Notes

Install with a flat-blade screwdriver sized to the slot width to avoid cam-out and head damage. De-energize any electrical enclosure or equipment panel fully before fastening or removing screws in live assemblies, following applicable NEC requirements. Do not overtighten into thin sheet metal, as the material can strip at the thread engagement point. Inspect the zinc coating before installation; discard any screws showing white corrosion or physical damage to the thread form.
