Value Collection 592148PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 592148PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive profile and fine-thread engagement. This screw features a 6-40 UNF thread size with full threading along its 5/16-inch length under head, driven by a 7/64-inch hex socket. Constructed from 18-8 austenitic stainless steel (Grade A2) with a bright uncoated finish, it provides reliable corrosion resistance in both indoor and outdoor service environments. It meets ASME/ANSI B18.3 and ASTM F837 fastener standards, making it suitable for applications where dimensional consistency and material traceability matter.

This screw is well suited for light mechanical assemblies, instrumentation panels, electrical enclosures, and precision equipment where a low-profile socket-drive fastener is required. The fine 6-40 UNF thread pitch provides strong clamping force in thin or tapped metal components. Typical installers include maintenance technicians, industrial assemblers, and field service professionals working on equipment that demands controlled torque in tight clearance areas. Minimum order quantity is 100 pieces per order.

Key Features

• 6-40 UNF fine thread for high clamp load in thin materials
• Fully threaded along the 5/16-inch length under head
• 7/64-inch hex socket drive for use with standard Allen keys or hex bits
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant and non-magnetic
• Bright uncoated finish — no plating to add dimensional variability
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw compatible with any tapped 6-40 UNF threaded hole requiring a 7/64-inch hex drive fastener.

Installation Notes

Install using a calibrated 7/64-inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless tapped holes. Do not exceed the rated torque range for 6-40 UNF stainless fasteners as specified by ASME/ANSI B18.3 guidelines.
