Value Collection 011455BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 011455BR is a hex socket cap screw sized 5/8-18 UNF with a 2-inch length under head. It is fully threaded along its entire shank and driven with a 1/2-inch hex key. The fastener is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and a consistent, low-reflectance appearance. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for high-strength bolted connections in mechanical assemblies, tooling, and industrial equipment. Licensed trades and maintenance mechanics install these fasteners where a recessed drive head and high tensile strength are required.

This screw is used in a wide range of industrial and mechanical applications including machine frames, fixtures, jigs, hydraulic manifolds, and structural assemblies where a flush or recessed head profile is preferred. Its fully threaded shank makes it especially well suited for shorter grip-length joints where full thread engagement throughout the fastened stack is needed. It is commonly specified in both OEM manufacturing and MRO replacement contexts.

Key Features

• 5/8-18 UNF thread form for fine-pitch engagement and reduced axial movement under vibration
• 2-inch length under head, fully threaded shank
• 1/2-inch hex socket drive for standard hex key or socket tooling
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion protection and reduces galling risk
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any 5/8-18 UNF tapped hole application requiring a high-strength alloy steel fastener with a recessed hex drive.

Installation Notes

Installation is performed with a calibrated torque wrench and the appropriate 1/2-inch hex key bit or Allen wrench. De-energize and lock out any equipment before accessing fastened assemblies. Apply thread lubricant or anti-seize as required by the assembly specification to achieve accurate clamp load from applied torque. Do not exceed the torque value specified by the equipment manufacturer or applicable engineering standard for this thread size and material grade.
