Value Collection 0648MST 6-32x3in Truss Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0648MST is a 6-32 x 3-inch truss head machine screw designed for secure mechanical fastening in metal and other rigid materials. The slotted drive accepts standard flat-blade screwdrivers, making it a practical choice for production assembly, maintenance, and repair tasks. Manufactured from steel with a zinc-plated finish, this screw meets the dimensional and performance requirements of ASME B18.6.3 and SAE J82. The broad, low-profile truss head distributes clamping load over a wider bearing surface than a standard pan or round head, reducing pull-through risk in thinner materials. Length is measured under the head. Licensed trade professionals and assembly technicians working across HVAC, electrical, and mechanical enclosure applications will find this a reliable inch-series fastener.

This screw suits a wide range of light to medium-duty fastening applications in residential and commercial settings. Typical uses include securing sheet metal panels, electrical enclosure covers, equipment access doors, and control board mounting hardware. The 6-32 thread is a standard unified coarse thread size commonly found in instrument panels, electronic assemblies, and light-gauge steel fabrications. The zinc plating provides moderate corrosion resistance suitable for indoor and protected environments. This item is sold individually but requires a minimum order quantity of 100 pieces.

• Slotted drive compatible with standard flat-blade screwdrivers and bits
• Steel construction, zinc-plated for moderate corrosion resistance in dry or protected environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material grade standards
• No washer included or required; ships without washer

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 6-32 threaded fastener with a truss head profile. Compatible with pre-tapped holes or hex nuts of the appropriate 6-32 thread specification.

Installation Notes

Install using a flat-blade screwdriver or appropriately sized slotted bit. Ensure the mating hole or nut is tapped to 6-32 specifications before driving to avoid cross-threading. Apply consistent, controlled torque — do not over-drive, as the slotted head is susceptible to cam-out under excessive force. For electrical enclosure work, follow applicable NEC guidelines for securing panel components.
