Value Collection 3728MST 3/8-16 Truss Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 3728MST is a 3/8-16 coarse-thread machine screw with a truss head and slotted drive, manufactured from steel with a zinc finish. The truss head profile is low and wide, distributing clamping load over a larger bearing surface than a standard pan or round head. At 1-3/4 inches length under head, this fastener is suited for applications requiring a secure threaded connection through moderate material thickness. It conforms to ASME B18.6.3 and SAE J82 standards, confirming dimensional and mechanical compliance for industrial and general mechanical assembly work. Installers in HVAC, electrical, plumbing, and general equipment maintenance will find this screw useful wherever a wide-bearing, slotted-drive fastener is called for.

This machine screw is appropriate for light-gauge sheet metal, equipment housings, junction boxes, and other assemblies where a broad head footprint is preferred. The 3/8-16 thread is a standard coarse-thread designation, compatible with tapped holes, threaded inserts, or hex nuts in the same size. The zinc finish provides a basic level of corrosion resistance suitable for indoor and protected outdoor environments. Trade professionals across mechanical, electrical, and HVAC disciplines regularly stock this size for field repairs and panel work.

Key Features

• Truss head profile provides a low, wide bearing surface to distribute clamp load
• 3/8-16 coarse thread for compatibility with standard tapped holes and hardware
• 1-3/4 inch length under head suits moderate-depth fastening applications
• Slotted drive works with standard flat-blade screwdrivers and bits
• Zinc finish offers basic corrosion resistance for indoor and protected environments
• Meets ASME B18.6.3 and SAE J82 dimensional and mechanical standards

Compatibility

Designed as a standard 3/8-16 coarse-thread machine screw for use in tapped holes, threaded inserts, or with matching hex nuts in general mechanical and electrical assembly applications.

Installation Notes

Installation requires a flat-blade screwdriver or bit sized to the slotted drive. Ensure the receiving hole is properly tapped to 3/8-16 before driving the fastener to avoid cross-threading. Power down all electrical equipment before fastening or removing screws in or near energized enclosures. Do not overtighten into thin-gauge material, as the wide truss head can distort soft substrates if excessive torque is applied.
