Holo-krome 73034 Hex Socket Cap Screw 10-32 Unf Alloy Steel

Product Description

The HOLO-KROME 73034 is a hex socket cap screw designed for applications requiring a compact, high-strength fastener with a recessed drive. Sized at 10-32 UNF with a 3/8-inch length under head, this screw is fully threaded and driven with a 5/32-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance in moderate environments while maintaining the mechanical strength expected from an ASME B18.3 and ASTM A574 compliant fastener. Machinists, millwrights, HVAC technicians, and assembly professionals rely on this style of cap screw for machine assembly, panel mounting, and equipment fabrication where a flush or low-profile fastener head is required.

This screw is suited for light industrial and mechanical assembly work in both residential and commercial settings. Its fine 10-32 UNF thread pitch provides superior thread engagement in tapped holes compared to coarse-thread equivalents, making it a preferred choice for precision equipment, control panel hardware, and thin-material fastening. The black oxide coating reduces light reflection and offers mild corrosion protection in dry or lightly oiled environments.

Key Features

• 10-32 UNF fine thread for superior thread engagement in tapped holes
• 3/8-inch length under head for shallow fastening applications
• Fully threaded shank for maximum thread engagement throughout the fastener length
• 5/32-inch hex drive accepts standard Allen or hex key tools
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish for mild corrosion resistance and low-reflectance appearance

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for any application requiring a 10-32 UNF fully threaded socket head fastener conforming to ASME B18.3.

Installation Notes

Installation requires a 5/32-inch hex key or Allen wrench; use a calibrated torque wrench where fastener preload is specified by the equipment manufacturer. Ensure the mating tapped hole is clean and free of debris before installation. Do not exceed the rated torque for the thread size and material grade. Follow applicable mechanical assembly standards and equipment service documentation when replacing fasteners in critical assemblies.
