Holo-krome 78044 Hex Socket Cap Screw 10-24 Unc

Product Description

The HOLO-KROME 78044 is a hex socket cap screw designed for secure mechanical fastening in applications where a recessed drive and high corrosion resistance are required. Threaded 10-24 UNC and measuring 7/8 inches under the head, this fastener is fully threaded and driven with a 5/32-inch hex key. Constructed from 18-8 stainless steel with a bright uncoated finish, it delivers solid resistance to rust and oxidation without a surface treatment adding dimensional variation. Machinists, millwrights, equipment assemblers, and maintenance technicians typically install this type of fastener where torque must be applied in tight clearance areas inaccessible to a standard hex head wrench.

This screw suits a wide range of light to medium-duty mechanical assemblies, including machine frames, enclosures, fixtures, brackets, and equipment panels. The 10-24 UNC thread form is a common coarse-thread standard found throughout industrial, HVAC, electrical, and plumbing equipment. The fully threaded configuration maximizes thread engagement in thin stock and short-depth tapped holes, making it a practical choice for assemblies where clamping length is limited.

Key Features

• 10-24 UNC thread size with full threading for maximum engagement
• 7/8-inch length under head suits moderate-depth fastening applications
• 5/32-inch hex socket drive for use with standard Allen or hex keys
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Bright uncoated finish maintains consistent dimensional tolerances
• Meets ASME B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or service fastener for any application specifying a 10-24 UNC hex socket cap screw in 18-8 stainless steel per ASME B18.3 and ASTM F837.

Installation Notes

Install using a calibrated 5/32-inch hex key or Allen wrench; ensure the driver is fully seated in the socket before applying torque to avoid rounding the drive recess. Verify the tapped hole is clean and free of debris before threading the screw in. Power down or de-energize any equipment before accessing fastener locations on live assemblies. Follow applicable mechanical and equipment codes for fastener torque requirements specific to the assembly being serviced.
