Value Collection MP99147 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION MP99147 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assembly work. Manufactured from Grade 8 steel with no finish coating applied, this fastener meets ASME B18.2.1 dimensional standards. The 5/8-11 UNC thread size and 1.5-inch length under head make it a common choice for bolted connections requiring reliable clamping force. Mechanics, millwrights, and maintenance technicians install these fasteners wherever a hex-drive bolted joint is specified under inch-series standards.

This cap screw is suited for general industrial and mechanical assembly, heavy equipment maintenance, and structural bolting where Grade 8 tensile strength is required. The uncoated finish is appropriate for dry indoor environments or applications where a specific coating or plating will be applied after assembly. Sold in a package quantity of 10, this part is stocked for maintenance shops, production lines, and field service kits that need reliable, spec-compliant Grade 8 fasteners on hand.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 5/8-11 UNC fully threaded configuration along the full shank length
• 1.5-inch length under head per ASME B18.2.1 dimensional standard
• Uncoated finish — no plating or coating applied
• Hex head drive accepts standard hex wrenches and sockets
• Packaged in quantities of 10 for bench stock and field use

Compatibility

Designed as a standard inch-series hex head cap screw for any bolted assembly specifying a 5/8-11 UNC Grade 8 fastener per ASME B18.2.1.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench, socket, or impact driver rated for the fastener size. De-energize and lock out all equipment before replacing fasteners in live mechanical assemblies. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as lubrication affects clamp load for a given torque value. Follow the equipment manufacturer torque specifications and applicable standards for the joint being assembled.
