Value Collection R64406344 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R64406344 is a hex socket cap screw designed for secure fastening in applications where a flush or recessed drive is required. The fastener features a 5/16-18 UNC thread size and measures 1.5 inches in length under the head. It is fully threaded from the head to the tip, maximizing thread engagement across the full length of the fastener. Constructed from 18-8 stainless steel with a bright, uncoated finish, this screw offers corrosion resistance suitable for both indoor and outdoor service environments. Installation requires a 0.25 inch hex drive key or Allen-type driver.

This socket cap screw is commonly used in mechanical assemblies, equipment fabrication, and maintenance applications across HVAC, plumbing, electrical, and general trade industries. Its 5/16-18 UNC thread pattern is a widely used coarse-thread standard, making it a practical stock item for field technicians and shop maintenance crews. The stainless steel construction makes it a preferred choice in environments with moisture exposure or chemical contact where carbon steel fasteners are not appropriate.

Key Features

• 5/16-18 UNC coarse-thread pattern for broad compatibility with standard tapped holes
• Fully threaded body maximizes thread engagement across the entire 1.5 inch length under head
• 18-8 stainless steel construction provides corrosion resistance in wet or chemically active environments
• Bright, uncoated finish maintains dimensional tolerance for precision fits
• 0.25 inch hex socket drive for use with standard Allen keys or hex bit drivers

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring a fastener of this thread size, length, and drive type.

Installation Notes

Installation is performed using a 0.25 inch hex key or hex socket bit torqued to the torque specification appropriate for 5/16-18 stainless steel fasteners as determined by the equipment manufacturer or applicable assembly standards. De-energize or shut down any equipment before replacing fasteners in live assemblies. Avoid cross-threading by hand-starting the screw before applying drive torque. Anti-seize compound may be considered when installing stainless steel fasteners into stainless tapped holes to prevent galling.
