The HOLO-KROME 06044 is an uncoated steel Allen nut threaded at 5/16-18 inches. Also referred to as a hex socket nut or cap nut, this fastener accepts a hex key for installation and removal in tight or recessed spaces where a standard wrench cannot reach. The 5/16 inches hex key drive and 5/16-18 inch thread size make it a direct fit for applications requiring a compact, flush, or recessed fastening profile. Manufactured from plain steel without a protective coating, this nut is suited for dry or controlled indoor environments. Technicians and tradespeople across plumbing, HVAC, and mechanical assembly use this type of fastener when clean tool access and secure clamping are both required.
This Allen nut is appropriate for use in light mechanical assemblies, equipment panels, enclosures, and structural brackets where a 5/16-18 inch thread is specified. Its uncoated steel construction keeps costs down for interior or protected installations. Packaged individually, it suits repair, replacement, or single-point assembly needs without requiring bulk purchase. HVAC, plumbing, and electrical tradespeople commonly stock these nuts for field repairs on equipment covers, access panels, and mounting hardware.
Designed for use with standard 5/16-18 inch threaded fastener applications in mechanical, HVAC, plumbing, and electrical assemblies requiring a hex socket nut drive style.
Installation requires a 5/16 inches hex key or Allen wrench. De-energize or shut off any equipment before accessing fasteners on powered assemblies. Inspect mating threads for damage or contamination before installation. Do not overtighten, as this can strip steel threads in softer mating materials.
