Value Collection 199713 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 199713 is a partially threaded hex socket cap screw designed for fastening applications that require corrosion-resistant hardware. It features a 5/16-18 UNC thread size and measures 1.75 inches in length under the head. Drive is a 1/4-inch hex socket. Constructed from 18-8 stainless steel, this fastener resists rust and oxidation in wet, humid, or chemically active environments. It is suited for mechanical assemblies, equipment mounting, and structural fastening tasks across a range of industries and field conditions.

This cap screw is used in applications where a recessed hex drive is preferred over external-drive fasteners, allowing flush or near-flush seating against a surface. The 5/16-18 UNC thread is a standard coarse-thread designation, making it compatible with common tapped holes and threaded inserts found in general mechanical, HVAC, plumbing, and electrical panel assemblies. Partial threading allows for better clamping force between joined materials.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 1.75-inch length under head for medium-depth fastening applications
• Partial threading design promotes strong clamping between mated surfaces
• 1/4-inch hex socket drive accepts standard hex keys and socket bits
• 18-8 stainless steel construction resists corrosion in wet and humid environments

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in general mechanical and trade assemblies requiring 18-8 stainless steel fasteners with a 1/4-inch hex drive.

Installation Notes

Install using a 1/4-inch hex key or hex socket bit. Ensure the mating tapped hole or threaded insert matches the 5/16-18 UNC thread specification before driving. De-energize or shut off any associated equipment before performing fastener work on live assemblies. Avoid cross-threading by starting the fastener by hand until it seats squarely before applying tool torque.
