Value Collection 592040PR Hex Socket Cap Screw 2-64 Unf

Product Description

The VALUE COLLECTION 592040PR is a hex socket cap screw threaded to the 2-64 UNF standard with a 5/16-inch length under head. The drive is a 5/64-inch hex socket, requiring an appropriately sized hex key or Allen driver for installation. Constructed from 18-8 austenitic stainless steel (Material Grade A2), this fastener resists corrosion in wet, chemical-exposed, and outdoor environments. It is fully threaded from the underside of the head to the tip. Machinists, millwrights, maintenance technicians, and precision assembly professionals install this type of fastener where a low-profile cap screw with reliable thread engagement is required in a compact clearance envelope.

The 592040PR is suited for light-duty precision assemblies where fine thread engagement and corrosion resistance are priorities. Fine-thread UNF fasteners deliver greater thread engagement per unit length compared to coarse-thread equivalents, making them well-suited for thin-walled or tapped-hole applications in metal components. Typical use cases include instrument panels, electronic enclosures, HVAC controls, electrical panels, and small mechanical assemblies where vibration resistance and stainless durability are required. This screw ships in multiples of 100 units per order minimum.

Key Features

• 2-64 UNF fine thread for higher thread engagement in compact assemblies
• 5/16-inch length under head suits shallow-depth tapped hole applications
• Fully threaded from head to tip maximizes thread engagement across the full shank
• 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance without plating
• 5/64-inch hex socket drive compatible with standard hex keys and bit drivers
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or service fastener for applications requiring a 2-64 UNF hex socket cap screw in stainless steel. Verify thread size, length under head, and drive size against the existing fastener or engineering specification before ordering.

Installation Notes

Installation requires a calibrated 5/64-inch hex key or matching bit driver. Verify the receiving tapped hole is clean and the thread form matches the 2-64 UNF specification before driving the screw. Avoid over-torquing fine-thread stainless fasteners into stainless tapped holes, as galling can occur without appropriate anti-seize compound. Power down or de-energize any assembly before fastener service where electrical components are involved.
