Value Collection 581483PS Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 581483PS is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and maintenance trades. Threaded at 3/8-16 UNC with a 7-inch length under head, this screw is partially threaded and driven with a 5/16-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light glare on the fastener surface. Weighing 0.23 pounds, it suits applications where a compact, strong fastener is needed without adding significant mass. This part meets ASME/ANSI B18.3 and ASTM A574 standards.

This socket cap screw is suited for use in machinery assembly, fixture fabrication, equipment repair, and structural fastening where a recessed drive profile is required. The 3/8-16 UNC thread is a coarse-thread specification commonly used in general industrial applications. The partial threading allows the unthreaded shank to act as a shoulder in through-hole configurations, which helps with alignment and load distribution. Technicians in mechanical maintenance, millwright, and general industrial trades regularly work with fasteners of this specification.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 7-inch length under head accommodates deeper through-hole and stacked-material applications
• Partially threaded shank aids in alignment and shear load distribution
• 5/16-inch hex socket drive for use with standard Allen or hex key tools
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any tapped hole or threaded insert meeting that thread specification. Conforms to ASME/ANSI B18.3 dimensional standards.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the screw. De-energize and lock out any equipment before replacing or installing fasteners in powered machinery, per standard LOTO procedures. Do not exceed the torque capacity of the alloy steel fastener by using improper or extended-handle tools without consulting applicable torque tables.
