Value Collection -48548-7 Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION -48548-7 is a partially threaded hex socket cap screw designed for high-strength fastening applications. It features a 5/8-18 UNF thread size and a 3-inch length under head, making it suitable for applications requiring precise thread engagement and reliable clamping force. Constructed from alloy steel with a black oxide finish, this screw offers solid mechanical strength and a baseline level of corrosion resistance. Drive size is 1/2 inch hex. This fastener is installed by machinists, maintenance technicians, and mechanical contractors working with structural assemblies and machinery.

This hex socket cap screw is used in industrial machinery, structural assemblies, and mechanical equipment where a recessed drive style is required to keep fastener heads flush or below the surface. The 5/8-18 UNF fine thread provides tighter clamping in applications where vibration resistance and precise torque control are critical. Suitable for both light industrial and heavy-duty mechanical assembly environments where alloy steel strength is specified.

Key Features

• 5/8-18 UNF fine thread for precise engagement and vibration resistance
• 3-inch length under head for deep fastening applications
• Partially threaded shank for shear-load bearing capability
• 1/2-inch hex socket drive for common Allen key or hex driver compatibility
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications specifying 5/8-18 UNF partially threaded hex socket cap screws per ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with fastener torque specifications for the application. Always ensure mating threads are clean and free of debris before installation. Use a properly sized 1/2-inch hex key or socket driver to avoid rounding the drive recess. Follow applicable ASME or equipment manufacturer torque guidelines for the fastener grade and application.
