Parallel blocks (pair) – 8 x 21 mm, 150 mm length by Metav IndustryLine

Parallel blocks for precise workholding and setup tasks on machine tables and inspection benches, offering stable support and high repeatability for small to medium assemblies.

• Hardened, finely ground special steel
• Height tolerance ±0.01 mm
• Length 150 mm for versatile setups

Consistent contact and measurable precision for setup work

These parallel blocks deliver repeatable contact surfaces thanks to finely ground faces and a heat-treated body. The compact cross-section of 8 x 21 mm combines rigidity with manoeuvrability, making them suitable for precise alignment, parallel clamping and reference positioning on machine tables or inspection fixtures. The declared height tolerance of ±0.01 mm ensures measurable reproducibility; when used as a support pair, the result is reduced set-up time and fewer position checks, which benefits productivity in medium-volume production environments.

Robust construction that eases workshop handling

Manufactured from special steel that has been hardened and finished to a flat, matte face, the blocks resist fretting and remain dimensionally stable under routine workshop use. The 150 mm length provides a useful span for supporting small assemblies and workpieces, while the modest cross-section allows tight placement between clamps or jaws. As a result, these blocks function both as precise datum supports during inspection and as reliable packing pieces for machining operations, combining durability with practical handling.

Production standards and practical conformity for quality control

Production adheres to recognised tolerancing practice with DIN ISO 2768 alignment in manufacture, which complements the declared height tolerance and supports integration into standardised quality routines. Supplied as a matched pair and finished to flatness suitable for reference work, the blocks are easy to include in inspection protocols or as part of first-article checks. For buyers seeking a dependable workshop standard, the combination of grind quality, material treatment and nominal tolerance provides an objective basis for selection and traceable results in daily use.
