Value Collection 011173P Hex Socket Cap Screw 1/4-28 Unf

Product Description

The Value Collection 011173P is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies, fixtures, and industrial equipment. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and a clean, low-profile appearance. It carries a 1/4-28 UNF thread size with a 3/16-inch hex drive and measures 1/2 inch in length under the head. Fully threaded along its entire shank length, it provides maximum thread engagement in shallow or through-hole applications. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and structural fastening tasks.

This screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and general mechanical maintenance. Its fine 28-TPI UNF thread pitch makes it well suited for thinner materials and applications where vibration resistance or precise thread engagement is required. Installers working with compact assemblies or close-tolerance components will find the 3/16-inch hex drive socket head appropriate for recessed or confined fastening locations.

Key Features

• 1/4-28 UNF fine thread for strong engagement and vibration resistance
• Fully threaded shank maximizes thread contact in shallow through-holes
• Alloy steel construction provides high tensile strength
• Black oxide finish offers moderate corrosion resistance and reduces light reflection
• 3/16-inch hex socket drive allows use of standard Allen keys or hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or general-purpose fastener for any application requiring a 1/4-28 UNF hex socket cap screw with a 1/2-inch length under head.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or tradesperson using a properly sized 3/16-inch hex key or socket bit driver. De-energize and lockout any equipment before fastener replacement to comply with applicable safety codes. Avoid over-torquing, which can strip threads or fracture the fastener head. Inspect mating threads for damage or debris before installation to ensure full seating.
