The VALUE COLLECTION R57001088 is a hex socket cap screw designed for fastening applications requiring a recessed drive interface and reliable clamping strength. It features a 5/8-11 UNC thread size and a length under head of 2.75 inches. The 0.5 inch hex drive accepts a standard Allen-style hex key or socket bit. Constructed from 18-8 stainless steel with a bright uncoated finish, this fastener resists corrosion in wet or mildly corrosive environments. It is commonly installed by maintenance technicians, pipefitters, millwrights, and general contractors across mechanical and structural assemblies.
This cap screw suits a wide range of general industrial, commercial, and trade applications where a clean socket-drive head profile is required. Typical install scenarios include machinery mounting, equipment frames, pipe flanges, and HVAC structural components where access to the fastener head is limited and a flush or low-profile drive is preferred. The 5/8-11 UNC coarse thread pattern provides strong thread engagement in both ferrous and non-ferrous tapped holes.
Designed as a standard 5/8-11 UNC hex socket cap screw suitable for use in any application requiring this thread size and drive configuration per ASME B18.3 socket cap screw standards.
Install using a calibrated torque wrench with the appropriate 0.5 inch hex key or hex socket bit. Ensure the tapped hole is clean and free of debris before threading. Follow applicable mechanical or structural codes for torque and fastener specification requirements. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation measures.
