Value Collection 015527BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015527BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural connections. The screw features a 1-8 UNC thread size and measures 2-1/4 inches in length under the head. It accepts a 3/4-inch hex drive and is fully threaded along its length. Manufactured from alloy steel with a black oxide finish, it resists corrosion and reduces surface reflectivity. This fastener meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for demanding load-bearing installations. Machinists, millwrights, and maintenance technicians are the typical installers.

This hex socket cap screw is suited for use in industrial equipment, machine frames, jigs, fixtures, and structural assemblies where a recessed drive and high clamping force are required. The coarse 1-8 UNC thread provides strong engagement in both steel and cast iron tapped holes. The black oxide coating is commonly used in indoor mechanical environments where light corrosion resistance and a low-profile appearance are preferred. Sold individually, this fastener fits applications requiring a single replacement or low-quantity procurement.

Key Features

• 1-8 UNC coarse thread for strong engagement in steel and cast iron
• 2-1/4 inch length under head for deep fastening reach
• 3/4-inch hex socket drive for high-torque installation with standard hex keys or socket tools
• Fully threaded for maximum thread engagement across the full shank length
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides light corrosion resistance and reduces glare in finished assemblies

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in any tapped hole or application conforming to ASME/ANSI B18.3 dimensional standards.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 3/4-inch hex key or socket drive. Ensure mating tapped holes are clean and free of debris before threading. Follow torque specifications published in ASME or equipment manufacturer documentation for the application and alloy grade. Never install fasteners into damaged or cross-threaded holes.
