Holo-krome 78038 Hex Socket Cap Screw 10-24 Unc Stainless

Product Description

The HOLO-KROME 78038 is a hex socket cap screw designed for secure mechanical fastening in applications where a low-profile, high-strength connection is required. Threaded 10-24 UNC with a 1/2-inch length under the head, this fastener is fully threaded and accepts a 5/32-inch hex drive. Constructed from 18-8 stainless steel with a bright, uncoated finish, it offers corrosion resistance suitable for both indoor and outdoor assemblies. It meets ASME B18.3 and ASTM F837 standards, making it appropriate for precision mechanical and structural fastening work across HVAC, plumbing, electrical panel, and general equipment applications.

This screw is used in light-duty to medium-duty mechanical assemblies where a socket-drive fastener is preferred over a hex-head bolt. Common install scenarios include equipment panel attachment, access cover mounting, and component bracketing in residential and commercial trade settings. The fully threaded design allows engagement along the entire shank length, which is useful in thin-material or through-hole applications. Installers in multiple trades use this fastener when access is limited and an Allen wrench or hex key driver is the practical tool.

Key Features

• 10-24 UNC thread size with 1/2-inch length under the head
• Fully threaded shank for maximum thread engagement
• 5/32-inch hex socket drive for Allen wrench or hex bit installation
• 18-8 stainless steel construction for corrosion resistance
• Bright, uncoated finish — no plating to chip or flake
• Meets ASME B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard 10-24 UNC hex socket cap screw for use in any mechanical assembly or equipment application requiring this thread size and drive type.

Installation Notes

Installation requires a 5/32-inch hex key or Allen-style socket bit. Power down or de-energize any equipment before fastening components near electrical or control assemblies. Stainless steel fasteners can be prone to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum mating parts. Follow applicable equipment manufacturer torque guidelines; do not over-torque, as stainless steel has lower shear strength than alloy steel fasteners of comparable size.
