Holo-krome 780140175 Hex Socket Cap Screw 6-32 Unc

Product Description

The HOLO-KROME 780140175 is a hex socket cap screw designed for precision fastening in mechanical assemblies, equipment enclosures, and structural connections where a low-profile, high-strength fastener is required. Threaded to 6-32 UNC with a 1.75-inch length under head and driven by a 7/64-inch hex key, this screw is partially threaded and manufactured from 18-8 stainless steel with a bright, uncoated finish. It meets ASME B18.3 and ASTM F837 standards, making it appropriate for applications with defined torque and dimensional requirements. Licensed contractors, millwrights, and maintenance technicians commonly install this fastener in corrosion-sensitive environments.

This screw is suited for residential and light commercial applications where stainless steel corrosion resistance is necessary, including HVAC equipment panels, pump housings, electrical enclosures, and general mechanical assemblies. The 6-32 UNC thread is a standard coarse thread size widely used in light-gauge metal, instrumentation, and equipment frame construction. The partial threading provides a stronger grip in through-hole applications and allows precise clamping without thread engagement in the clearance zone.

Key Features

• 6-32 UNC thread for compatibility with standard coarse-thread tapped holes in light-gauge assemblies
• 1.75-inch length under head accommodates moderate stack depths with partial threading for clean clamping
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor-exposed environments
• Bright uncoated finish maintains dimensional tolerances without added coating thickness
• Meets ASME B18.3 and ASTM F837 fastener standards for dimensional and mechanical conformance
• 7/64-inch hex socket drive for use with standard hex keys or socket drivers

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for mechanical assemblies requiring 6-32 UNC coarse-thread hex socket cap screws in stainless steel per ASME B18.3 and ASTM F837.

Installation Notes

Install using a calibrated 7/64-inch hex key or hex bit driver. Power down or de-energize any equipment before accessing fastener locations inside electrical or HVAC enclosures. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is a known risk with stainless steel fasteners. Apply an anti-seize compound to the threads when installing into stainless or aluminum tapped holes to prevent cold-welding.
