Value Collection 592153PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 592153PR is a hex socket cap screw designed for precision fastening applications requiring a compact, tool-accessible drive. Threaded 6-40 UNF with a 5/8 inch length under head, this fastener is fully threaded along its entire shank. The 7/64 inch hex drive accepts a standard Allen key or hex bit driver. Constructed from 18-8 austenitic stainless steel (Material Grade A2), it resists corrosion in wet, chemical-exposed, or outdoor environments. It meets ASME/ANSI B18.3 and ASTM F837 dimensional and mechanical standards, making it a code-recognizable choice for instrumentation, mechanical assemblies, and light structural connections.

This screw suits applications where a low-profile socket head is required in tight clearance areas. Common uses include equipment panels, HVAC component housings, electrical enclosures, pump assemblies, and plumbing fixtures where thread engagement and corrosion resistance are priorities. The 6-40 UNF thread pitch provides finer thread engagement than coarse-series fasteners, making it well suited for thin-material or precision-tapped applications. Minimum order quantity is 100 units per order.

Key Features

• 6-40 UNF fully threaded shank for maximum thread engagement in shallow blind holes
• 5/8 inch length under head for consistent grip in standard panel and housing applications
• 7/64 inch hex socket drive for Allen key or hex bit installation in confined spaces
• 18-8 austenitic stainless steel (Grade A2) construction for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard 6-40 UNF hex socket cap screw suitable for tapped holes conforming to ASME/ANSI B18.3 specifications in mechanical, electrical, and HVAC equipment assemblies.

Installation Notes

Installation requires a 7/64 inch hex key or Allen-drive bit. Verify the mating tapped hole is clean and correctly sized for 6-40 UNF thread engagement before driving the fastener. Do not overtighten stainless steel fasteners into stainless tapped holes without anti-seize compound, as galling can occur. Follow applicable mechanical or equipment manufacturer torque guidance for the specific assembly.
