Value Collection 837293PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 837293PR is a hex socket cap screw designed for precision fastening applications requiring a fine-thread profile. It features a 3/8-24 UNF thread size, a 1-1/4 inch length under head, and is fully threaded along its entire shank. The screw is driven with a 5/16 inch hex key. Constructed from alloy steel with a zinc-plated finish, it delivers reliable mechanical strength and basic corrosion resistance. This fastener meets ASTM B695 specifications, making it suitable for industrial, mechanical, and maintenance applications. It is sold individually per package with a minimum order quantity of 10 units.

This cap screw is used in mechanical assemblies, equipment fabrication, and maintenance repair operations across a wide range of industries. Its fine UNF thread pitch provides strong thread engagement and resistance to loosening under vibration, making it appropriate for metal-to-metal joints in machinery, fixtures, and structural assemblies. Machinists, millwrights, maintenance technicians, and fabricators commonly specify this fastener type when a flush or low-profile clamping head is required.

Key Features

• 3/8-24 UNF fine-thread profile for strong thread engagement and vibration resistance
• 1-1/4 inch length under head, fully threaded for maximum thread contact
• 5/16 inch hex socket drive for use with standard hex keys or Allen-type bit drivers
• Alloy steel construction for high tensile and shear strength
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• Meets ASTM B695 fastener standard

Compatibility

Designed as a standard UNF hex socket cap screw for use in any tapped or threaded hole sized for 3/8-24 thread in metal assemblies and mechanical components.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with torque requirements for the specific joint and material. Always de-energize or lock out equipment before replacing or tightening fasteners in powered assemblies. Use a properly sized 5/16 inch hex key or socket bit to avoid rounding the drive recess. Do not over-torque — consult engineering data for the specific alloy grade and joint material when torque values are critical.
