Holo-krome 86288 Hex Socket Cap Screw 6-32 Unc

Product Description

The HOLO-KROME 86288 is a hex socket cap screw designed for secure, high-torque fastening in tight-clearance applications where a standard hex head wrench cannot fit. It features a 6-32 UNC thread size and measures 1-1/4 inches in length under the head, with partial threading along the shank. The drive is a 7/64-inch internal hex socket, engaged with an Allen wrench or hex bit driver. Constructed from alloy steel with a black oxide finish, this screw offers improved corrosion resistance and reduced light reflection compared to bare steel. Licensed trades and industrial maintenance technicians install this fastener in mechanical assemblies, electrical enclosures, HVAC equipment, and other precision applications.

This screw is suited for use in both light commercial and residential mechanical systems where a low-profile, high-strength fastening point is required. The 6-32 UNC thread is a standard coarse-thread designation common in electrical panel assemblies, equipment frames, and control box hardware. Partial threading provides a clamped bearing surface on the unthreaded shank, which is appropriate for applications requiring precise alignment between mated components. This screw is sold in multiples of 100 per order.

Key Features

• 6-32 UNC thread for compatibility with standard coarse-thread tapped holes
• 1-1/4 inches length under head with partial threading for positive clamping
• 7/64-inch hex socket drive for use with Allen wrenches or hex bit drivers
• Alloy steel construction meets ASME B18.3 and ASTM A574 standards
• Black oxide finish provides moderate corrosion resistance and low-glare appearance

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw for use in any application requiring a 6-32 UNC tapped hole with 1-1/4-inch fastener length.

Installation Notes

Install using a 7/64-inch hex key or matching hex bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not over-torque alloy socket cap screws in thin material or plastic-tapped bosses. Follow applicable mechanical or electrical codes when installing fasteners inside energized enclosures — de-energize and lock out equipment before beginning work.
