Category

T-bolts, also referred to as T-head bolts or T-slot bolts, are specialized fasteners designed for use with T-slot tracks and machine tool tables. The distinctive T-shaped head allows the bolt to slide into the slot, while the head itself engages the slot to prevent rotation during tightening — a feature that in some designs (e.g., DIN 186) is enhanced by a square neck beneath the head, similar to carriage bolts. This design enables quick positioning and secure clamping of fixtures, workpieces, and components without requiring a second tool to hold the bolt.

Key Features

  • T-shaped head slides into T-slot tracks for easy positioning.

  • The T-shaped head itself engages the slot to prevent spinning during tightening.

  • Allows for adjustable mounting without drilling additional holes.

  • Ideal for applications requiring frequent repositioning.

  • Provides secure clamping for machine tooling and fixtures.
