Value Collection 198786 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 198786 is a fully threaded hex socket cap screw designed for fastening applications that require a recessed drive and corrosion-resistant construction. It carries a 5/16-18 UNC thread and measures 1 inch in length under the head. Drive engagement is through a 1/4 inch internal hex socket. The screw is manufactured from 18-8 stainless steel, which provides reliable resistance to rust and oxidation in both indoor and outdoor environments. This type of fastener is typically installed by machinists, millwrights, plumbers, or mechanical contractors working on equipment assemblies, pipe supports, enclosures, and structural brackets.

This cap screw is suited for use in light to medium-duty mechanical assemblies where a flush or countersunk fastening profile is needed and a hex key wrench can be used for torquing. Common applications include equipment mounting, panel assembly, pipe hanger hardware, and general fabrication work. The 5/16-18 UNC thread form is a widely used coarse-thread standard compatible with standard tapped holes and hex nuts of the same specification.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank provides maximum thread engagement across the entire 1 inch length under head
• 1/4 inch internal hex socket drive allows use with standard Allen or hex key wrenches
• 18-8 stainless steel construction resists corrosion and oxidation without plating
• Compact 0.029 pound per-unit weight suitable for high-count fastener applications

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw compatible with any application or tapped hole calling for that thread specification and a 1/4 inch hex drive.

Installation Notes

Installation requires a 1/4 inch hex key or Allen wrench; an L-key, T-handle, or bit driver of the correct size should be used to avoid stripping the socket. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply thread-locking compound or anti-seize as required by the application and applicable mechanical codes. Do not exceed the rated torque range for 5/16-18 18-8 stainless fasteners, as over-torquing stainless steel screws can cause galling or failure.
