Guide rail block (14TO18) – S45C, M5 T‑nut, set of 4 by Vertex

The Guide rail block is a compact clamping component designed for use with linear guide rails and small fixture assemblies in workshops and production jigs.

• Compact 18 × 20 × 16 mm footprint
• Manufactured from S45C carbon steel
• M5 T‑nut for secure fastening
• Supplied as a set of 4 pieces

Secure, repeatable alignment for small fixtures

The compact block delivers a consistent locating function where space is limited: its 18 × 20 × 16 mm profile minimises intrusion into assemblies while providing a stable contact face for rails and mating parts. The integrated M5 T‑nut allows a positive threaded connection in standard T‑slot systems, ensuring repeatable alignment under varying loads. For production contexts where fixture changeovers must be fast and precise, this component reduces setup time and contributes to process reliability.

Robust material choice that supports machining and longevity

Constructed from S45C, a medium carbon steel grade, the component offers a pragmatic balance between strength and machinability. That material choice allows finishing operations and minor custom machining if different contact geometries are required, while maintaining the mechanical integrity expected in clamping applications. Where fixtures are subject to repeated assembly cycles, the material's properties help to extend service life and lower lifecycle costs compared with softer alternatives.

Compact set for modular assembly and easy replacement

Supplied as a set of 4, the blocks simplify procurement for multi-point fixtures and modular jigs, avoiding the need to source individual items. The small mass (approx. 0.13 kg per set) and standardised thread interface make integration straightforward on machine tables and bespoke fixtures. Because the design focuses on function rather than ornament, the component serves well in production, maintenance and prototype settings where space economy and dependable clamping are priorities.
