Value Collection 40222 Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 40222 is a hex socket cap screw designed for applications requiring a precise, high-strength threaded fastener. Sized at 1/4-28 UNF with a 1-3/4 inch length under head, this screw is partially threaded and driven with a 3/16 inch hex key. It is manufactured from alloy steel with a black oxide finish coating, which provides mild corrosion resistance and reduces light reflection. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming it is rated for industrial-grade use. Mechanical assemblers, maintenance technicians, and trade professionals working with machinery, fixtures, or equipment frames will find this a standard replacement or assembly fastener.

This screw is suited for use in light to medium industrial assemblies, machine component mounting, and equipment maintenance applications where a fine-thread 1/4-28 UNF socket cap screw is specified. The fine thread pitch provides stronger resistance to loosening under vibration compared to coarse thread equivalents of the same diameter. It is commonly installed in metal-to-metal assemblies and tapped steel or aluminum components. This screw ships in single-piece quantity with a minimum order of 50 units.

Key Features

• 1/4-28 UNF fine thread for vibration-resistant fastening in metal assemblies
• 1-3/4 inch length under head, partially threaded shank
• 3/16 inch hex drive for standard Allen key or hex bit installation
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide coating provides mild corrosion resistance and low-glare surface
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or assembly fastener for any application calling for a 1/4-28 UNF hex socket cap screw with a 1-3/4 inch length under head conforming to ASME/ANSI B18.3.

Installation Notes

Installation is performed using a 3/16 inch hex key or Allen-drive bit. Ensure the receiving threaded hole is clean and free of debris before driving. De-energize or lock out any equipment before accessing fastener locations on live machinery per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque range for 1/4-28 alloy steel fasteners as specified in your assembly documentation.
