Value Collection 011185P Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 011185P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and equipment. Manufactured from alloy steel with a black oxide coating, this fastener provides solid corrosion resistance in indoor and light-duty industrial environments. It features a 1/4-28 UNF thread size with a 1-1/2 inch length under head and is partially threaded to engage a defined grip range. Drive size is 3/16 inch hex socket, requiring a standard hex key or Allen driver. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical fastening where dimensional and strength compliance is required.

This cap screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical enclosure hardware, plumbing fixture mounting, and general mechanical maintenance. The fine 28-thread-per-inch UNF pitch provides precise thread engagement and greater clamping force in thin-wall or close-tolerance applications. It is appropriate for both original equipment assembly and field repair work where an alloy steel, black oxide socket cap screw of this specification is called out.

Key Features

• 1/4-28 UNF fine thread for precise engagement and high clamping force
• 1-1/2 inch length under head, partially threaded
• 3/16 inch hex socket drive for use with standard Allen or hex key tools
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish for corrosion resistance in indoor and protected environments
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies and equipment requiring a 1/4-28 UNF partially threaded hex socket cap screw with a 1-1/2 inch length under head and 3/16 inch drive.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with fastener torque and thread engagement requirements. Power down and de-energize all equipment before accessing any fastened assemblies. Use a properly sized 3/16 inch hex key or Allen driver to avoid rounding the drive socket. Follow applicable equipment manufacturer specifications and relevant codes for fastener installation in structural or load-bearing applications.
