Holo-krome 78114 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The HOLO-KROME 78114 is a hex socket cap screw designed for mechanical assemblies and structural fastening applications that require corrosion resistance and reliable clamping force. The fastener features a 1/2-13 UNC thread form and measures 1-1/4 inches in length under the head. Drive engagement is achieved with a 3/8 inch hex key. Manufactured from 18-8 stainless steel with a bright, uncoated finish, the screw meets ASME B18.3 and ASTM F837 standards. It is fully threaded along its entire length, making it well suited for through-hole and short-grip applications where full thread engagement is needed.

This cap screw fits typical applications in HVAC equipment mounting, plumbing fixture assembly, light structural connections, and general industrial maintenance where stainless steel fasteners are specified to resist moisture, mild chemicals, or outdoor exposure. The 1/2-13 UNC thread size is common in medium-duty equipment frames and panel assemblies. Licensed trades and maintenance professionals regularly specify 18-8 stainless socket cap screws where standard carbon steel fasteners would corrode or contaminate the surrounding materials.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard tapped holes and nuts
• 1-1/4 inch length under head with full threading along entire shank
• 3/8 inch hex socket drive for use with standard hex keys and bit sets
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Bright uncoated finish meets ASME B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw suitable for use in any application requiring an ASME B18.3 compliant fastener in 18-8 stainless steel with a 3/8 inch hex drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or socket bit. Ensure mating threads are clean and free of debris before driving. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern. Apply appropriate anti-seize compound when fastening into aluminum or other reactive metals to prevent galling.
