Value Collection MPKP44116 Hex Cap Screw 5/8-11 X 2.5 in Grade 8

Product Description

The VALUE COLLECTION MPKP44116 is a 5/8-11 hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc-plated finish, this partially threaded fastener meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The coarse UNC thread pattern at 5/8-11 provides reliable engagement in steel and iron components. Licensed trades and maintenance professionals will find this screw appropriate for heavy equipment, framing hardware, and mechanical system mounting where tensile strength and corrosion resistance are both required.

This fastener is suited for use in commercial and industrial settings where high-strength fasteners are specified. The partial threading provides a smooth shank section for applications requiring bolt-in-clearance-hole configurations, allowing the clamped material to draw tight without thread interference. The zinc plating offers baseline corrosion protection appropriate for indoor and dry-use environments. Mechanical contractors, millwrights, and maintenance technicians commonly use Grade 8 cap screws of this type when torquing into tapped holes or using nuts and washers on structural connections.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile and proof load requirements
• Zinc-plated finish provides corrosion resistance for standard service environments
• Partial threading allows shank to span clearance holes without thread binding
• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Sold in a package quantity of 10 with a minimum order quantity of 1

Compatibility

Designed as a standard UNC hex head cap screw for use with 5/8-11 tapped holes, standard hex nuts, and compatible washers in steel and iron assemblies requiring Grade 8 tensile strength.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using an appropriately rated torque wrench calibrated to Grade 8 fastener specifications. Ensure mating threads are clean and free of debris before installation. Do not substitute a lower-grade fastener in any application that specifies Grade 8. Follow applicable industry or equipment manufacturer torque tables for the fastener size when final torque values are not provided in the input data for this part.
