Value Collection 837165PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 837165PR is a hex socket cap screw designed for mechanical fastening applications requiring a recessed hex drive. Threaded to the 1/4-20 UNC standard, this fastener measures 2.5 inches in length under the head and accepts a 3/16-inch hex key. It is partially threaded, which provides better clamping force in bolted joint assemblies. Constructed from alloy steel with a zinc-plated finish, it delivers solid tensile strength with basic corrosion resistance in dry or mildly humid environments. It is a common fastener choice for machine assembly, HVAC equipment panels, electrical enclosures, and mechanical system components.

This screw is suited for general industrial and trade applications where a socket cap fastener is specified. The 1/4-20 UNC thread pattern is one of the most widely used coarse-thread sizes in North American trade work, making it compatible with a broad range of tapped holes and threaded inserts. Typical applications include equipment frames, junction boxes, pump housings, and access panel hardware. Installation requires a 3/16-inch hex key or hex driver bit.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 2.5-inch length under head suits medium-depth clamping applications
• 3/16-inch hex socket drive for use with standard Allen keys or hex driver bits
• Partially threaded shank improves clamping load in bolted joints
• Alloy steel construction provides high tensile strength
• Zinc-plated finish offers basic corrosion resistance in dry environments

Compatibility

Designed as an OEM-style replacement or service fastener for any application specifying a 1/4-20 UNC hex socket cap screw with a 2.5-inch length under head. Meets ASTM B695 standard.

Installation Notes

Install with a 3/16-inch hex key or socket driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Do not overtighten — follow the torque specification of the assembly being serviced, not a generic value. In electrical or HVAC enclosure work, de-energize equipment before removing or replacing fasteners on panels or access covers.
