Value Collection 015535BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 015535BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. It carries a 1-8 UNC thread with a 3/4-inch hex drive and measures 3.25 inches in length under the head. The screw is fully threaded along its entire shank, manufactured from alloy steel, and finished with a black oxide coating for mild corrosion resistance. It conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards. This type of fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working with heavy equipment or precision assemblies.

This socket cap screw is suited for applications requiring controlled torque and a low-profile, flush-mount head. The 1-8 UNC coarse thread is well suited for use in steel and iron, where thread engagement needs to resist vibration and dynamic loading. Typical install scenarios include machine frames, hydraulic component mounting, pump housings, and structural steel assemblies where access space is limited and a hex key drive is preferred over an external hex head fastener.

Key Features

• 1-8 UNC coarse thread for reliable engagement in steel and iron substrates
• Fully threaded shank along the entire 3.25-inch length under head
• 3/4-inch hex socket drive allows high torque input with standard hex keys or Allen drivers
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduces surface glare
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw for any application requiring a 1-8 UNC fully threaded fastener with a 3/4-inch hex drive and 3.25-inch length under head.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical contractors using a 3/4-inch hex key or socket driver. De-energize, depressurize, or lock out the equipment before removing or installing fasteners in live assemblies. Apply thread lubricant or anti-seize compound as appropriate for the application environment. Torque to the value specified by the equipment manufacturer or applicable ASME or OEM fastener specification.
