Value Collection MPC703517 Hex Cap Screw 3/4-16 X 3 in Grade 8

Product Description

The VALUE COLLECTION MPC703517 is a 3/4-16 hex head cap screw designed for high-strength fastening applications across industrial, mechanical, and trade environments. This screw measures 3 inches under the head and features a unified fine thread (UNF) pattern at 3/4-16, making it suited for joints that require precise clamping force and resistance to loosening under vibration. Manufactured from Grade 8 steel in an uncoated finish, it delivers a minimum proof load and tensile strength consistent with SAE Grade 8 specifications. The partial threading is appropriate for clamping two or more components with a bearing surface at the shank. Sold in packages of 10.

This fastener is used in heavy-duty mechanical assemblies, equipment mounting, structural connections, and maintenance repair operations where a high-strength inch-series hex cap screw is required. Typical applications include agricultural equipment, industrial machinery, automotive frames, and trade fabrication work. The fine thread series improves thread engagement in thin material sections and provides tighter torque control compared to coarse thread equivalents. Installers in HVAC, plumbing, and general mechanical service use Grade 8 cap screws when spec sheets call for high-tensile fasteners in inch-dimensioned hardware.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/4-16 UNF fine thread for improved torque precision and vibration resistance
• 3-inch length under head, partially threaded for proper clamping without full thread engagement through stack
• Uncoated finish — suitable for applications where coating is not required or where field finishing will be applied
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• Packaged in quantities of 10 per pack

Compatibility

Designed as a standard inch-series hex head cap screw conforming to ASME B18.2.1, compatible with 3/4-16 UNF threaded holes and corresponding Grade 8 or equivalent nuts and washers in general mechanical and industrial assembly applications.

Installation Notes

Installation should be performed by qualified mechanical tradespeople familiar with fastener torque requirements for Grade 8 hardware. Always consult the equipment manufacturer torque specification table for the fastener grade and size before tightening. Ensure mating threads are clean, undamaged, and free of debris before installation. Use a calibrated torque wrench to achieve proper clamp load without exceeding the fastener's proof load.
