Parallel supports, pair (12 x 20 mm, 150 mm) — hardened, ground special steel

The Parallel supports, pair (12 x 20 mm, 150 mm) serve as rigid, precision reference blocks for machining set-ups, inspection benches and fixture assembly in industrial workshops

• Precision ground and hardened steel
• Height tolerance ±0.01 mm
• Compact 12 x 20 mm cross-section
• Supplied as a matched pair

Consistent reference surfaces for repeatable set-ups

These parallels provide a stable datum thanks to a finely ground and hardened surface that resists wear and preserves geometry under repeated clamping. The combination of special steel and precise finishing reduces deformation and maintains flatness across the support faces, which improves repeatability when relocating components between machines or inspection stations. Engineers benefit from lower set-up time and fewer alignment checks when using stable reference blocks.

Precise dimensions that simplify inspection and jig building

With a nominal cross-section of 12 x 20 mm and a nominal length of 150 mm, the supports offer the ideal compromise between reach and rigidity for typical workshop tasks. The specified height tolerance of ±0.01 mm gives a clear, verifiable basis for dimensional setups and ensures compatibility with tight fixture requirements. Conformity to DIN ISO 2768 provides further assurance that these parts integrate consistently into standardised assemblies and quality-control procedures.

Matched pair delivery for symmetry and safer clamping

Supplied as a pair, the blocks allow symmetric support of workpieces, reducing torsion and uneven loading during milling, drilling or measurement. A matched pair simplifies repetitive production sequences and fixture layouts, where equal bearing heights are essential for achieving geometric stability. The modest mass and compact form factor make them easy to position while still offering the stiffness expected in demanding shop-floor environments.

Durable construction for long service life

Manufactured from special steel that is finely ground and hardened, the supports withstand the mechanical stresses of daily use and maintain reference accuracy over time. The surface finish aids in reducing micro-slippage beneath workpieces, while the hardened substrate resists indentations from clamps or sharp edges. These attributes combine to lower the total cost of ownership through extended service intervals and fewer replacements.
