Holo-krome 06038 Allen Nut 8-32 Unc Steel Black Oxide

Product Description

The HOLO-KROME 06038 is a hex-drive allen nut designed for use with 8-32 UNC threaded fastener applications. Made from steel with a black oxide finish, this nut provides corrosion resistance and a consistent surface for high-contact assemblies. It uses a 3/16 inch hex key drive and has an overall height of 0.273 inches. The right-hand thread direction and Class 2B thread fit ensure reliable engagement with standard UNC fasteners. It meets ASME B1.1 and ASTM A194/A194M Grade 2H standards. Machinists, millwrights, and mechanical contractors install this fastener in light mechanical assemblies, fixtures, and equipment panels requiring an internal hex-drive nut.

This allen nut is suited for industrial, commercial, and light manufacturing applications where a flush or recessed hex-drive nut is needed. The 8-32 UNC thread size is commonly found in instrument panels, machinery guards, electrical enclosures, and small mechanical assemblies. The black oxide steel construction holds up in indoor and sheltered environments where moderate corrosion resistance is acceptable.

Key Features

• 8-32 UNC right-hand thread with Class 2B fit for standard fastener engagement
• 3/16 inch hex key drive for installation with a standard allen wrench
• Black oxide finish on steel for surface protection and low-glare appearance
• Overall height of 0.273 inches for compact, low-profile installations
• Meets ASME B1.1 and ASTM A194/A194M Grade 2H standards

Compatibility

Designed for use with 8-32 UNC threaded studs, bolts, and rods following ASME B1.1 thread standards. Suitable for general industrial and mechanical assemblies requiring an internal hex-drive nut at this thread size.

Installation Notes

Install using a 3/16 inch hex key or allen wrench; do not substitute a larger key as this may strip the drive socket. Ensure the mating threaded fastener is clean and free of burrs before engagement. Torque to the fastener assembly specification for the application — no torque value is specified for this part in the available data. Observe applicable ASME or facility fastener standards for the assembly being serviced.
