Parallel stop M318.243.1 — Parallel block 12 × 40 × 100 mm, hardened and ground (Metav IndustryLine)

The Parallel stop M318.243.1 is a hardened, ground parallel block designed to secure and align workpieces in machine slots with H8 tolerance, suited for 12 mm slot widths in production and toolroom environments

• Hardened, ground special steel construction
• Precisely ground height 40 ±0.0055 mm
• Delivered as a matched pair for symmetric locating
• Suited for machine slots with H8 tolerance

Consistent precision that keeps setups repeatable

Manufactured from special steel that is ground and hardened, this precision parallel provides a stable datum for positioning and clamping. The stated nominal tolerance 0/-0.02 mm with height classification IT5 ensures repeatable alignment across batches, reducing rework and setup variation. The robust finish resists wear and helps maintain contact geometry over time, which translates into fewer measurement deviations and steadier machining results.

Balanced clamping through matched-pair delivery

Delivered as a matched pair, the components are selected and finished to work together, avoiding asymmetric clamping forces that can distort thin or delicate workpieces. At a length of 100 mm and a thickness of 12 mm, the blocks offer a balance between reach and rigidity for common machine workholding. The pair format streamlines fixturing for parallel jaws, fixtures or vice setups and accelerates changeovers on the shop floor.

Clear dimensional data for reliable integration

Critical dimensions are provided for direct integration into existing tooling: height 40 ±0.0055 mm, length 100 mm, weight 0.8 kg. The compact footprint simplifies placement in confined slots while the precise height tolerance (IT5) helps preserve parallelism when used as a reference gauge. Where process capability or assembly repeatability is measured, this component supplies a verifiable datum that aligns with quality-control expectations.

Designed for machine slots with industrial tolerances

The set is explicitly intended for use in machine slots with tolerance H8, making it compatible with standardised slot geometries in milling and machining centres. The hardened and ground surfaces reduce the risk of plastic deformation under clamping forces, maintaining datum integrity even in routine production conditions. This combination of material and finishing supports sustained positional accuracy and consistent workpiece support.

Practical advantages for everyday workshop use

Beyond material and precision, the product is optimised for practical workshop handling: the ground faces simplify seating and alignment, the matched-pair supply reduces setup uncertainty, and the moderate mass supports stable clamping without excessive handling difficulty. The SKU and identification allow traceability for stock management and quality documentation in procurement and inspection routines.
