Parallel supports (pair) M318.239.17 — 150 mm, hardened and precision ground

The Parallel supports (pair) M318.239.17 provide a compact, stable elevation solution for machining, inspection and fixture work, combining workshop-friendly length with workshop-grade flatness and repeatability

• Hardened, finely ground special steel
• Precise height tolerance ±0.01 mm
• Classic 150 mm length for workshop use
• Pair supplied for stable workholding

Secure, measurable precision for setup and inspection

The M318.239.17 parallels deliver precision where repeatability matters: the height is specified at ±0.01 mm, a tolerance that supports consistent setups in inspection and machining routines. Compliance with DIN ISO 2768 gives a standardised reference for dimensional accuracy across mating parts and fixtures; this measurability reduces rework and shortens setup times by eliminating uncertainty in reference surfaces. The clear numeric tolerance and norm reference make the component suitable for quality-conscious workshops and small-series production where traceable performance is required.

Durable material and finish that preserves accuracy

Manufactured from special steel that is finely ground and hardened, the supports combine surface quality and wear resistance to maintain flatness after repeated use. The precision-ground faces ensure contact that minimises point loading and reduces micro-movement during milling, drilling or inspection. As a consequence, the lifetime of the datum remains predictable: fewer touch-ups and less need for frequent re-grinding keep maintenance effort low while preserving positional accuracy in jigs and vices.

Practical length and handling for everyday workshop tasks

At 150 mm overall length and supplied as a pair, these parallels are sized for typical vice and fixture work, offering a balance between reach and stiffness. With a mass of 0.47 kg per pair, handling is straightforward while stability on the machine table is retained. The rectangular cross-section (14 x 17 mm) suits a wide range of clamping arrangements and permits neat stacking for stepped setups. In short, the geometry supports efficient fixturing in milling, drilling and inspection without complex adaptations.

FAQ

What are parallels used for in a workshop?
Parallels are used to raise and support workpieces squarely in vices and fixtures; the M318.239.17 parallels provide stable datum faces for milling, drilling and inspection tasks.

How accurate are these parallels for precision setups?
The M318.239.17 pair is specified with a height tolerance of ±0.01 mm and is produced to DIN ISO 2768 guidance, making them suitable for repeatable workshop measurements and setup.

What material are the parallels made from and why does it matter?
These parallels are made from special steel that is finely ground and hardened; the material and finish preserve flatness and resist wear, maintaining accuracy over repeated use.

Can the parallels be stacked for stepped setups?
Yes, the rectangular cross-section and consistent ground faces allow neat stacking to create stepped support arrangements for a variety of clamping configurations.

Are these parallels suitable for inspection as well as machining?
Yes, the precision-ground surfaces and the defined tolerance make the M318.239.17 pair appropriate for both inspection references and everyday machining fixtures.
