Value Collection 30023 Steel T-slot Bolt 5/8-11 Uncoated

Product Description

The VALUE COLLECTION 30023 is a steel T-slot bolt designed for securing workpieces and fixtures to T-slotted machine tables, jigs, and workholding setups. The bolt features a 5/8-11 UNC thread with a 2-inch thread length and fits a 5/8-inch T-slot width. The head profile — 1-3/32 inches wide and 11/32 inches tall — is engineered to slide into standard T-slots and lock in place under clamping load. Made from C-1045 steel with an uncoated finish, this bolt is intended for use in machine shops, fabrication environments, and industrial fixture applications. Machinists, tool-and-die technicians, and manufacturing maintenance personnel are the typical installers.

This bolt is suited for use on milling machine tables, grinding fixtures, drill press tables, and other workholding platforms that use standard 5/8-inch T-slots. The 5-1/2-inch length under the head accommodates stacked clamps, step blocks, and strap clamp setups commonly used in manual and CNC machining operations. The Class 3 thread fit provides a close tolerance suitable for demanding fixture applications where positional accuracy matters.

Key Features

• 5/8-11 UNC thread with Class 3 thread fit for close-tolerance clamping applications
• 2-inch thread length provides sufficient engagement for standard strap clamp nuts and studs
• 5/8-inch slot width fits common T-slotted machine tables and fixture plates
• 5-1/2-inch length under head accommodates multi-piece clamp stacks and step blocks
• C-1045 steel construction offers solid tensile strength for workholding loads
• Uncoated finish — no plating to add dimensional variation at the head seating surface

Compatibility

Designed as an OEM-style replacement or direct-use T-slot bolt for machine tables and fixture systems with a standard 5/8-inch T-slot width.

Installation Notes

Install this bolt by sliding the head into the T-slot channel before loading the workpiece or clamp assembly — the head cannot be inserted from above once the slot is obstructed. Verify that the slot width and depth match the bolt head dimensions before tightening. Follow the machine or fixture manufacturer torque guidelines and applicable shop safety procedures when securing workpieces for machining operations. Inspect threads for damage or contamination before reuse.
