Value Collection R56000998 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R56000998 is a hex socket cap screw designed for fastening applications that require corrosion resistance and reliable clamping strength. Manufactured from 316 stainless steel with a bright, uncoated finish, this cap screw carries a 5/8-11 UNC thread and measures 2-1/4 inches in length under the head. Drive engagement is through a 1/2-inch internal hex socket, requiring a standard Allen or hex key drive. The 316 stainless alloy provides superior resistance to chlorides and oxidizing environments compared to 304-grade fasteners, making it a practical choice for industrial, marine, and process piping applications where fastener corrosion is a concern.

This socket cap screw is suited for use in mechanical assemblies, equipment mounting, and structural connections across commercial and industrial settings. The 5/8-11 UNC coarse thread pitch is the standard for this diameter in inch-fastener applications and accepts commonly available 5/8-11 nuts and threaded inserts. Typical installers include millwrights, pipefitters, maintenance mechanics, and general industrial tradespeople working on equipment requiring stainless fasteners.

Key Features

• 316 stainless steel construction for enhanced chloride and corrosion resistance
• 5/8-11 UNC coarse thread for broad compatibility with standard inch-series hardware
• 2-1/4-inch length under head suits moderate-depth fastening applications
• 1/2-inch hex socket drive allows high torque input with a standard Allen wrench or socket driver
• Bright, uncoated finish maintains dimensional precision without added coating thickness

Compatibility

Designed as a standard inch-series hex socket cap screw for use with 5/8-11 UNC threaded holes, nuts, and inserts in mechanical and structural assemblies.

Installation Notes

Installation of socket cap screws in this size class is typically performed by a qualified mechanic or millwright. Ensure the mating threaded hole or nut meets the 5/8-11 UNC specification before installation. Consult applicable equipment torque requirements and relevant industry standards before final tightening. Use a properly sized 1/2-inch hex key or Allen socket drive to avoid rounding the drive recess.
