Holo-krome 720003352 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The HOLO-KROME 720003352 is a hex socket cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. With a 3/4-10 UNC thread size and a 5/8-inch hex drive, this screw delivers reliable torque transfer and secure clamping force. The 8-1/2-inch length under head accommodates deep fastening requirements where longer engagement is necessary. Manufactured from alloy steel and finished with a black oxide coating, it resists corrosion in moderate environments while maintaining high tensile strength. This fastener meets ASME B18.3 and ASTM A574 standards. It is partially threaded, which supports accurate shear load distribution in bolted connections. Machinists, millwrights, and mechanical contractors are the typical installers.

This hex socket cap screw is suited for use in heavy equipment assembly, machine frames, tooling fixtures, and other applications where a high-strength, recessed-drive fastener is required. The 3/4-10 UNC coarse thread pattern is widely used in general industrial applications and offers fast assembly with good resistance to cross-threading. The partial threading design makes it appropriate for applications that require a smooth shank section for precise alignment or shear load transfer. Both shop and field installations are common.

Key Features

• 3/4-10 UNC coarse thread for broad industrial compatibility
• 8-1/2-inch length under head supports deep-reach fastening requirements
• 5/8-inch hex socket drive for high-torque installation with standard Allen tooling
• Alloy steel construction meets ASTM A574 high-strength fastener specification
• Black oxide finish provides moderate corrosion resistance and reduced light reflection
• Partially threaded shank for accurate alignment and shear load applications
• Conforms to ASME B18.3 dimensional standard

Compatibility

Designed as a standard ASME B18.3 hex socket cap screw suitable for use in any application requiring a 3/4-10 UNC partially threaded fastener with an 8-1/2-inch length under head and a 5/8-inch hex drive.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical contractors using a 5/8-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for 3/4-10 alloy steel fasteners. Black oxide fasteners used in outdoor or high-moisture environments may benefit from supplemental thread lubricant or anti-seize compound to prevent galling.
