Value Collection 97146 Hex Head Cap Screw 5/8-11 X 1-1/4 in Grade 5

Product Description

The VALUE COLLECTION 97146 is a fully threaded hex head cap screw designed for general industrial and mechanical assembly applications. Sized at 5/8-11 UNC thread with a 1-1/4 inch length under head, this fastener is manufactured from Grade 5 steel in an uncoated finish, making it suitable for use in dry or protected environments where a bare steel surface is acceptable. It conforms to ASME B18.2.1 standards, ensuring consistent dimensional tolerances across the production run. This screw is a common choice for structural connections, machinery frames, and equipment assembly where UNC thread engagement and Grade 5 strength ratings are specified by the job or the OEM drawing.

These hex head cap screws are used across a wide range of trade and industrial applications, including HVAC equipment mounting, mechanical system brackets, plumbing support structures, and general fabrication work. The 5/8-11 UNC thread size is one of the most widely used heavy fastener sizes in commercial and industrial construction. Sold in a pack of 25, this SKU is well suited for service vans, shop stock, or project-specific hardware pulls where mid-volume quantities are needed without committing to a full box.

Key Features

• 5/8-11 UNC thread form per ASME B18.2.1 dimensional standard
• Fully threaded along the 1-1/4 inch length under head
• Grade 5 steel construction for medium-strength fastening applications
• Uncoated finish suitable for indoor or protected installations
• Packed in quantities of 25 per package

Compatibility

Designed as a standard UNC hex head cap screw for use in any application requiring a 5/8-11 thread size and Grade 5 steel strength rating per ASME B18.2.1.

Installation Notes

Installation is performed with a standard hex wrench or socket drive sized for a 5/8-11 hex head fastener. Follow the torque specifications called out in the equipment manufacturer documentation or applicable structural drawings, as this prompt does not supply product-specific torque values. Ensure mating threads are clean and free of debris before installation. Uncoated fasteners should not be used in wet or corrosive environments without additional protective measures such as anti-seize compound or a coated alternative.
