Value Collection 592347PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 592347PR is a hex socket cap screw designed for precision fastening applications requiring fine thread engagement and corrosion resistance. The screw features a 3/8-24 UNF thread size with a 1-3/4 inch length under head and is partially threaded to allow controlled clamping force in bolted joint assemblies. Driven with a 5/16 inch hex key, it is manufactured from 18-8 austenitic stainless steel (Grade A2) and left uncoated, making it suitable for environments where oxidation resistance and moderate chemical exposure are concerns. Machinists, millwrights, and maintenance mechanics are the typical installers.

This screw is used in mechanical assemblies, machine frames, fixtures, and equipment panels where a fine-thread UNF fastener is specified. The 3/8-24 UNF thread pitch provides tighter thread engagement compared to coarse-thread equivalents, making it well suited for thin-walled sections or applications subject to vibration. The partially threaded shank improves shear load distribution in bolted connections. Typical installations occur in both light industrial and commercial equipment maintenance environments.

Key Features

• 3/8-24 UNF fine thread for tight engagement and vibration resistance
• 1-3/4 inch length under head for standard clamping depth
• 5/16 inch hex socket drive for Allen key or hex bit installation
• Partially threaded shank improves shear load performance in bolted joints
• 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance without coating
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for mechanical assemblies specifying a 3/8-24 UNF hex socket cap screw with 1-3/4 inch length under head per ASME/ANSI B18.3 standards.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a 5/16 inch hex key or hex socket bit. De-energize and lock out all equipment before fastener replacement or installation per applicable lockout/tagout procedures. Apply appropriate thread lubricant or anti-seize if required by the assembly specification to prevent galling, which is a known risk with stainless steel fasteners. Do not exceed the torque specification called out in the equipment manufacturer documentation.
