Value Collection 581848BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581848BR is a hex socket cap screw designed for high-strength fastening applications requiring precise thread engagement. It features a 1-14 UNF thread profile, a 5-inch length under head, and a 3/4-inch hex drive socket. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces surface reflectivity. This screw is partially threaded, keeping the unthreaded shank intact for shear-load applications. It meets ASME/ANSI B18.3 and ASTM A574 standards and is suited for mechanical assembly work performed by millwrights, maintenance technicians, and industrial tradespeople.

This cap screw is appropriate for use in heavy mechanical assemblies, industrial equipment mounting, and structural fastening where a fine unified thread (UNF) is specified for tighter thread-fit tolerances. The 1-14 UNF designation makes it a typical choice when vibration resistance or precise clamp load control is required. The partially threaded shank allows the bolt body to pass through clearance holes before engaging the mating threads, which is common in flanged or bolted joint assemblies found in industrial and manufacturing environments.

Key Features

• 1-14 UNF thread — fine thread pitch for improved vibration resistance and precise clamping
• 5-inch length under head — accommodates thick stack-ups or deep engagement requirements
• 3/4-inch hex socket drive for use with standard hex keys or socket drive tools
• Partially threaded shank suitable for shear-load and clearance-hole applications
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate surface protection and low reflectivity

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial and mechanical assemblies specifying a 1-14 UNF hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by qualified millwrights or maintenance technicians familiar with fastener torque specifications for the specific joint design. Always verify thread engagement depth and mating material compatibility before installation. Use a calibrated torque wrench sized for a 3/4-inch hex drive and follow the applicable engineering or equipment torque specifications — no torque value is specified in the product data and none should be assumed. Clean mating threads and inspect for damage before assembly.
