Setting ring M313.029 — 29 mm setting ring, hardened and lapped gauge steel

Setting ring M313.029 is a precision ring gauge designed for setting and checking measuring instruments and go/no‑go fixtures in workshop and inspection environments.

• 29 mm nominal diameter gauge
• Hardened, lapped gauge steel
• Conforms to DIN 2250 / DIN 286
• Form C seating for secure location

Precision where it matters: consistent reference for gauges and fixtures

The 29 mm setting ring serves as a stable reference for adjusting micrometres, comparators and dial gauges. Manufactured from hardened and lapped gauge steel, its contact faces present a low‑wear surface that preserves dimensional integrity over repeated use. Conformity to DIN 2250 together with the DIN 286, JS 3 tolerance class provides a clear, certified performance level for quality control routines, reducing uncertainty in adjustment tasks and ensuring interchangeability between instruments.

Designed for practical workshop use and fast seating

The Form C geometry gives reliable seating and quick engagement in common holding systems and fixture designs. Its compact form factor and robust finish make it suitable for frequent handling in production or calibration labs, where ease of seating and stability under manual or light mechanical engagement improve throughput. The lapping process applied to the ring’s measuring face minimises surface roughness and micro‑asperities, which in turn reduces measurement scatter during repeated set‑ups.

Built to standards: clear traceability and inspection confidence

As an engineered gauge produced for metrological use, the ring aligns with established inspection protocols: the JS 3 tolerance band ensures predictable deviation margins when compared to nominal size, simplifying pass/fail assessments and documentation. The use of recognised standards supports traceable measurement chains and helps meet internal and customer audit requirements, contributing to efficient quality assurance processes.

Material and durability: low maintenance, long service life

Constructed from gauge steel, hardened and lapped, the ring offers a balance of wear resistance and machinability that suits frequent calibration cycles. The finish minimises corrosion risk in typical workshop atmospheres and reduces the need for frequent rework; when handled correctly and stored with basic care, the component maintains its metrological properties, reducing lifecycle costs and downtime.
