Parallel stop M318.246.2 — Parallel block for 18 mm machine T‑slots, 18 x 60 x 120 mm (Metav IndustryLine)

The M318.246.2 parallel stop provides secure, repeatable workpiece location for machining and fixture set‑ups, designed specifically for 18 mm slot widths in metalworking environments

• Hardened, ground special steel construction
• Designed for 18 mm machine T‑slots
• Delivered as a matched pair
• Height tolerance IT5 for consistent locating

Repeatable precision for everyday machining

The M318.246.2 is manufactured from special steel, ground and hardened to deliver consistent seating and abrasion resistance. The nominal height is specified as 60 ±0.0065 mm, with a nominal tolerance of 0/-0.02 mm (height IT5), which supports tightly controlled positioning and low variation between set‑ups. Such dimensional discipline translates into fewer reworks and predictable process capability on the shop floor, making it suitable for batch production and repeat operations.

Robust construction that stays true under load

Built as a compact yet substantial stop (18 x 60 x 120 mm), the unit provides high stiffness and stable reference faces when clamping or indexing components. Supplied as a matched pair, the blocks ensure parallelism without additional selection or matching at the machine, simplifying fixture preparation and reducing set‑up time. The solid construction and ground faces support reliable clamping in milling, drilling and other machining processes where secure location is essential.

Designed to integrate with standard slot systems

This parallel block is intended for machine grooves with tolerance H8, making it compatible with common T‑slot specifications found on machine tables and fixtures. The 18 mm thickness is matched to the slot width, so the component locates positively and resists lateral play. By using a dedicated locating element tailored to the slot tolerance, repeatability improves and measuring or adjustment cycles are shortened, which increases throughput in production environments.

Practical benefits for workshop and tooling use

Beyond raw dimensions, the product delivers operational advantages: ground faces for direct contact with workpieces, hardened substrate for longevity and a geometry that suits clamping and indexing tasks. The combination of precision machining and robustness means the blocks serve equally well for fixture building, repetitive set‑ups and as permanent stops in small to medium workholding systems. The measured weight and compact format simplify handling and storage between uses.
