Value Collection 592063PR Hex Socket Cap Screw 3-56 Unf

Product Description

The VALUE COLLECTION 592063PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive interface and reliable corrosion resistance. This screw features a 3-56 UNF thread size with a 3/4 inch length under the head and a 5/64 inch hex drive. Constructed from 18-8 stainless steel (Austenitic Grade A2), it delivers strong resistance to rust and oxidation in both indoor and outdoor environments. The fully threaded shank provides consistent thread engagement along the entire usable length. This fastener meets ASME/ANSI B18.3 and ASTM F837 standards, making it suitable for applications where dimensional and material compliance is required.

This screw is used in light mechanical assemblies, instrumentation, electronics enclosures, and precision equipment where a small-diameter, fine-thread fastener is needed. The 3-56 UNF thread pitch is common in miniature machine components and assemblies where fine thread engagement and vibration resistance are priorities. Installers working in HVAC controls, electrical panel fabrication, pump assemblies, and similar trade environments will find this fastener appropriate for securing small components where torque control and thread integrity are critical.

Key Features

• 3-56 UNF thread size for fine-pitch, vibration-resistant fastening in miniature assemblies
• 5/64 inch hex socket drive for use with standard hex keys or Allen drivers
• 3/4 inch length under head provides adequate thread engagement in typical thin-panel applications
• Fully threaded shank maximizes thread contact along the entire grip length
• 18-8 stainless steel construction, Austenitic Grade A2, resists rust and corrosion
• Compliant with ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 3-56 UNF hex socket cap screw with a 3/4 inch length under head and 5/64 inch drive in 18-8 stainless steel.

Installation Notes

Install using a calibrated 5/64 inch hex key or Allen driver to avoid rounding the socket. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque for a size 3 stainless steel screw, as over-torquing can cause galling or thread stripping in stainless-to-stainless applications. Consider applying an anti-seize compound when threading into stainless steel tapped holes to reduce the risk of galling.
