Value Collection 5016MST 1/2-13x1 Truss Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 5016MST is a 1/2-13 x 1 inch truss head machine screw designed for general mechanical fastening applications. It features a slotted drive and is manufactured from steel with a zinc finish for basic corrosion resistance. The truss head profile delivers a wider, lower head than a standard pan or round head, distributing clamping load over a larger bearing surface. This screw conforms to ASME B18.6.3 and SAE J82 standards, making it suitable for use in controlled manufacturing, maintenance, and repair environments where dimensional compliance is required.

This machine screw is used in light to medium industrial assembly, equipment maintenance, and mechanical repair work across HVAC, electrical, and general trade applications. The 1/2-13 thread pitch is a coarse Unified National thread, commonly tapped into steel, aluminum, and thermoplastic housings. It is well suited for through-bolt and tapped-hole installations where a low-profile head and standard slotted drive are specified. Installed by maintenance technicians, millwrights, and trade professionals working on equipment panels, brackets, and enclosures.

Key Features

• Truss head profile provides a wide, low-profile bearing surface for distributed clamping load
• Slotted drive compatible with standard flat-blade screwdrivers and bit sets
• 1/2-13 coarse UNC thread for reliable engagement in tapped holes
• Steel construction with zinc finish for basic corrosion resistance in dry or low-moisture environments
• Conforms to ASME B18.6.3 and SAE J82 dimensional standards
• Without washer configuration for clean, direct seating against the workpiece

Compatibility

Designed as a standard 1/2-13 UNC coarse-thread machine screw for use in any tapped hole or with a standard 1/2-13 nut, consistent with ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Install using a flat-blade screwdriver or slotted bit rated for 1/2-inch fasteners. Ensure the mating tapped hole or nut is clean and free of debris before driving. De-energize any electrical equipment and relieve system pressure before fastening or removing screws in live assemblies. Do not exceed the torque capacity appropriate for the material grade and thread engagement depth.
