Holo-krome 73050 Hex Socket Cap Screw 10-32 Unf Alloy Steel

Product Description

The HOLO-KROME 73050 is a hex socket cap screw designed for high-strength fastening applications where a flush or low-profile head and precise torque control are required. It features a 10-32 UNF thread and a 1.75-inch length under head, with a 5/32-inch hex drive socket. Constructed from alloy steel and finished with a black oxide coating, this fastener delivers good corrosion resistance in moderate environments while maintaining the material strength needed for demanding mechanical assemblies. It is partially threaded, following ASME B18.3 and ASTM A574 standards. Installation professionals in industrial maintenance, mechanical assembly, HVAC equipment fabrication, and electrical enclosure work regularly use this screw type.

This fastener is suited for applications requiring fine-thread engagement in ferrous and non-ferrous components where vibration resistance and precise load control matter. The 10-32 UNF thread pitch is commonly found in instrument panels, electrical enclosures, pump housings, and light structural assemblies. The black oxide finish makes it a common choice in assemblies where moderate corrosion resistance and a low-reflectance appearance are needed. This screw ships in multiples of 100 units per the minimum order requirement, making it practical for shop stock and production-line replenishment.

Key Features

• 10-32 UNF fine thread for strong engagement and vibration resistance
• 1.75-inch length under head, partially threaded for precise grip-length control
• 5/32-inch hex drive socket compatible with standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides moderate corrosion resistance and low-reflectance appearance
• Conforms to ASME B18.3 dimensional standard for socket cap screws

Compatibility

Designed as an OEM-style replacement and standard-stock hex socket cap screw for mechanical assemblies requiring a 10-32 UNF partially threaded fastener per ASME B18.3 and ASTM A574 specifications.

Installation Notes

Installation is performed with a 5/32-inch hex key or hex bit driver torqued to the assembly specification for ASTM A574 alloy steel socket cap screws at this thread size. De-energize and lock out any equipment before accessing fastened assemblies per applicable safety codes. Avoid mixing with stainless or plated fasteners in the same joint without verifying galvanic compatibility. Inspect threads in the mating component before installation to ensure clean engagement and avoid galling.
