Value Collection 592087PR Hex Socket Cap Screw 4-48 Unf

Product Description

The VALUE COLLECTION 592087PR is a fully threaded hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Sized at 4-48 UNF with a 1/4-inch length under head and a 3/32-inch hex drive, this fastener is manufactured from 18-8 austenitic stainless steel (Material Grade A2) and left uncoated for a bright finish. It conforms to ASME/ANSI B18.3 and ASTM F837 standards, making it suitable for applications where dimensional consistency and corrosion resistance are required. Machinists, maintenance technicians, and assembly professionals working with small-form hardware will find this screw appropriate for tight-clearance installations.

This fastener is suited for light mechanical assemblies, instrument enclosures, small equipment housings, and precision machine components where a fine-thread UNF profile is specified. The 4-48 UNF thread designation provides higher thread engagement per inch compared to coarse-thread equivalents, which improves holding strength in thin materials. The stainless steel construction resists rust and mild corrosion, making it usable in both indoor and moderately wet environments. Sold in multiples of 100 per order with a package quantity of 1.

Key Features

• 4-48 UNF fully threaded profile for fine-thread engagement in thin or precision materials
• 3/32-inch hex socket drive for use with standard hex keys or Allen drivers
• 1/4-inch length under head for shallow fastening applications
• 18-8 austenitic stainless steel (Grade A2) construction for corrosion resistance
• Bright/uncoated finish — no additional plating that could affect dimensional tolerance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style or replacement hex socket cap screw for precision assemblies, instruments, and mechanical components specifying a 4-48 UNF thread size with a 1/4-inch grip length.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a 3/32-inch hex key or T-handle driver. Ensure the mating threaded hole is clean and free of debris before driving the screw. Do not overtighten in thin or soft base materials, as fine-thread fasteners in small diameters are susceptible to thread stripping. Apply thread-locking compound if vibration resistance is required for the application.
