Value Collection 837297PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 837297PR is a partially threaded hex socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and general industrial applications. Machined from alloy steel with a zinc-plated finish for corrosion resistance, this screw features a 3/8-24 UNF thread form and measures 1-3/4 inches under the head. Drive engagement is through a 5/16-inch internal hex socket, compatible with standard hex keys and socket drivers. This fastener meets ASTM B695 standards and is suited for applications requiring fine thread engagement and reliable clamping force.

This cap screw is appropriate for residential and commercial maintenance, industrial equipment assembly, and machine repair work. The 3/8-24 UNF fine thread pitch provides higher thread engagement per inch compared to coarse thread equivalents, making it well suited for tapped holes in harder materials or where vibration resistance is a priority. Installers in HVAC, mechanical, and general trade work commonly use this screw when securing panels, brackets, or component assemblies requiring a flush or recessed fastener head profile.

Key Features

• 3/8-24 UNF fine thread for high engagement and vibration resistance
• 1-3/4 inch length under head for adequate grip in medium-depth applications
• 5/16-inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction for high tensile strength
• Zinc-plated coating meets ASTM B695 for corrosion protection
• Partially threaded shank for precise alignment in clearance-hole applications

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring a 3/8-24 UNF hex socket cap screw with a 1-3/4-inch length under head and 5/16-inch drive.

Installation Notes

Installation requires a 5/16-inch hex key or socket driver. Power down or de-energize any equipment before removing or replacing fasteners in live assemblies. Do not exceed the rated torque range for the thread size and material being fastened into; consult applicable torque charts for 3/8-24 alloy steel cap screws. Inspect the receiving threads for damage or contamination before installation to prevent galling or cross-threading.
