Value Collection 1508CH2 Hex Head Cap Screw 1/4-28 X 1/2 in

Product Description

The VALUE COLLECTION 1508CH2 is a fully threaded hex head cap screw engineered to ASME B18.2.1 and SAE J429 standards. It features a 1/4-28 UNF thread size with a 1/2 inch length under head, manufactured from Grade 2 steel with a zinc plating finish for basic corrosion resistance. This fastener is driven with a 7/16 inch hex key and is suited for general-purpose mechanical assemblies. Licensed tradespeople and maintenance technicians specify Grade 2 zinc-plated fasteners across a wide range of light-duty mechanical and structural connections in HVAC equipment, plumbing fixtures, and electrical enclosures.

The 1508CH2 is appropriate for use in residential and light commercial applications where a standard-strength inch-series fastener is required. Its fully threaded shank provides consistent clamping engagement across the full grip length. This fastener is commonly used in equipment panels, bracket assemblies, access covers, and component mounting in trade installations. Sold individually per package unit with a minimum order quantity of 100 pieces.

Key Features

• 1/4-28 UNF thread — fine thread series for tighter thread engagement in thin or precision materials
• 1/2 inch length under head — compact profile for shallow clearance applications
• Fully threaded shank — maximum thread engagement across the entire fastener length
• Grade 2 steel construction — meets SAE J429 material requirements for general-purpose fasteners
• Zinc-plated finish — provides baseline corrosion protection for indoor and controlled-environment use
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws

Compatibility

Designed as a standard inch-series hex head cap screw for general mechanical assemblies requiring a 1/4-28 UNF thread and 1/2 inch under-head length in Grade 2 steel.

Installation Notes

Installation is performed with a 7/16 inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before fastening. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners as specified by the applicable equipment manufacturer or relevant standards. For installations subject to vibration or outdoor exposure, evaluate whether a higher grade or additional corrosion protection is required.
