Value Collection 837175PR Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 837175PR is a hex socket cap screw designed for precision fastening applications requiring a fine-thread profile. Machined from alloy steel and finished with a zinc-plated coating for corrosion resistance, this screw features a 1/4-28 UNF thread size, a 5/8-inch length under head, and a 3/16-inch hex drive. The fully threaded shank provides maximum thread engagement across the full usable length. This fastener is suited for mechanical assemblies, equipment maintenance, and production environments where a fine-thread, high-strength cap screw is specified.

This screw is appropriate for residential and commercial mechanical assemblies, HVAC equipment mounting, panel fabrication, and general trade applications where 1/4-28 UNF fine-thread fasteners are called out. The zinc-plated finish provides a baseline level of corrosion protection suitable for indoor and dry service environments. These screws are sold in minimum order quantities of 100 units, making them well-suited for shop stock, fleet maintenance kits, and production-run use by electricians, HVAC technicians, and mechanical contractors.

Key Features

• 1/4-28 UNF fine-thread profile for precise torque control and resistance to loosening under vibration
• Fully threaded shank maximizes thread engagement with mating components
• 3/16-inch hex socket drive compatible with standard hex keys and socket drivers
• Alloy steel construction provides higher strength compared to standard carbon steel fasteners
• Zinc-plated coating per ASTM B695 offers corrosion resistance in dry indoor service conditions
• Minimum order quantity of 100 units supports bulk stocking for production or service fleets

Compatibility

Designed as a standard 1/4-28 UNF hex socket cap screw for use in any application specifying that thread size, drive type, and length under head. No specific equipment or model compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using a calibrated hex key or socket driver sized to the 3/16-inch drive. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque specification called out in the equipment service manual for 1/4-28 UNF fasteners in the given material. Inspect the zinc-plated finish before installation and discard any fasteners showing corrosion, thread damage, or deformation.
