Value Collection 20022 Steel T-slot Bolt 1/2-13 Uncoated

Product Description

The VALUE COLLECTION 20022 is a steel T-slot bolt designed for use in machine tool tables, fixturing systems, and workholding setups that require a secure, low-profile fastener seated in a T-slot channel. This bolt features a 1/2-13 UNC thread with a 1-1/2 inch thread length and a 5 inch length under the head. It is manufactured from Grade C-1045 steel to a Class 3 thread fit and is supplied uncoated. Machinists, toolmakers, and fixture builders install this hardware when securing workpieces or fixture components to slotted tables and jigs.

This T-slot bolt is suited for use in industrial and job-shop environments where a 1/2 inch slot width is required. Typical applications include CNC machining centers, manual mills, drill press tables, welding fixture plates, and other precision workholding installations. The 7/8 inch head width and 9/32 inch head height are dimensioned to seat flush within standard 1/2 inch T-slot profiles, keeping the bolt head captured in the channel while a nut or clamp is tightened from above.

Key Features

• 1/2-13 UNC thread with 1-1/2 inch thread length for broad clamp and strap compatibility
• 5 inch length under head accommodates thick fixture plates and stacked workholding components
• Grade C-1045 steel construction provides solid tensile strength for fixturing loads
• Class 3 thread fit delivers tight tolerance engagement with standard hex nuts and T-nuts
• Uncoated finish allows for field coating or use as-is in dry shop environments
• Head dimensions — 7/8 inch width, 9/32 inch height — sized to fit 1/2 inch T-slot profiles

Compatibility

Designed as a standard replacement or stock fastener for machine tables, fixture plates, and workholding systems that use a 1/2 inch T-slot profile with 1/2-13 UNC threaded hardware.

Installation Notes

Slide the bolt head into the T-slot channel before assembling the fixture or workholding stack — the head cannot be inserted once surrounding components are in place. Tighten the mating nut to the torque specification required by the fixturing system or machine tool manufacturer. Inspect the slot channel for burrs or debris before installation to ensure the head seats and rotates freely. This fastener is installed by machinists and toolmakers following standard shop practices; no specialized tools beyond a wrench or socket are required.
