Value Collection 014124PS Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 014124PS is a hex socket cap screw designed for fastening applications requiring corrosion resistance and reliable clamping strength. Threaded to 5/16-18 UNC, it measures 2.5 inches in length under the head and is driven with a 1/4 inch hex key. Constructed from Grade 316 stainless steel with a bright, uncoated finish, it is well suited for environments where moisture, chemicals, or salt exposure are concerns. Machinists, maintenance technicians, and trade professionals use this fastener in mechanical assemblies, equipment mounting, and structural connections where standard carbon steel hardware would corrode prematurely.

This screw is appropriate for residential and commercial applications across HVAC, plumbing, electrical, and industrial maintenance work. The 5/16-18 UNC thread form is a common coarse-thread standard found in a wide range of mechanical assemblies, equipment frames, and panel enclosures. Grade 316 stainless steel offers superior resistance to chlorides compared to Grade 304, making it a preferred choice in coastal, chemical, or wet-service environments. The 1/4 inch hex drive allows use with standard hex keys and hex-bit drivers widely available in trade toolkits.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 2.5 inch length under head suits medium-depth fastening applications
• Grade 316 stainless steel construction for enhanced corrosion resistance
• 1/4 inch hex socket drive compatible with standard Allen keys and hex-bit drivers
• Bright uncoated finish with no added plating that could alter thread tolerances

Compatibility

Designed as a standard UNC hex socket cap screw for use in any application requiring a 5/16-18 threaded fastener with a 2.5 inch grip length and 1/4 inch hex drive.

Installation Notes

Installation requires a 1/4 inch hex key or hex-bit driver rated for the torque requirements of the assembly. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not exceed the torque limits specified for Grade 316 stainless steel fasteners at this thread size, as overtightening can gall stainless threads. Apply an anti-seize compound to the threads if the screw will be installed in a high-temperature or marine environment to prevent thread galling during future removal.
