Precise workpiece stops for consistent positioning
Workpiece stops provide a fixed reference point that ensures exact and repeatable placement of raw parts in machines and fixtures, improving dimensional consistency and reducing setup time by eliminating manual alignment. These positioners are used to define the zero point for subsequent operations such as milling, drilling and turning, and they prevent unwanted movement like slipping, rotation or axial shift during clamping and machining. Available in adjustable, magnetic and precision-ground variants, they suit varying geometries and high-volume production where process reliability and fast changeovers are essential, featuring benefits for fixtures and jigs as well as for spindle and vice-mounted applications. They support reproducible tolerances, faster throughput and greater process security.
100mm Universal Jaws With Soft Stop For Irregular Parts, 145x38x49mm - Vertex
Combine a soft stop for irregular components with precision to 0.01 mm and a compact footprint to achieve reliable clamping and consistent measurement results in daily workshop use. Order the Vertex Universal Jaws directly via Metav Werkzeuge or ask our consultants for fitting and compatibility advice. Vertex Universal Jaws VWSJ-R100 — universal caliper jaws with soft stop and precision contact The Vertex Universal Jaws VWSJ-R100 are replacement jaws for precision calipers, engineered to secure uneven or delicate workpieces while preserving repeatable measurement contact in inspection and assembly tasks. Soft stop for irregular workpieces Compatible with calipers 100–110 mm Precision to 0.01 mm Compact dimensions 145 x 38 x 49 mm Improve measurement repeatability with precision contact Replacing worn or generic jaws with a purpose-designed set offers an immediate gain in repeatability. The VWSJ-R100 provides a precision 0.01 mm contact surface that reduces measurement scatter when used with calipers having a jaw width of 100–110 mm. The controlled contact force delivered by the integrated soft stop minimises deformation of delicate parts and lessens the need for repeated checks, thereby improving throughput in quality-control routines. Streamline inspection workflows with a compact retrofit A compact footprint of 145 x 38 x 49 mm means these jaws integrate without obstructing access to the workpiece or measuring scale, supporting faster setup and clearer reading. The design enables quick replacement on compatible calipers and keeps handling straightforward during repetitive measurement sequences. As a practical result, inspection stations benefit from reduced downtime and more consistent data capture during batch checks. Protect sensitive components while maintaining clamp reliability The inclusion of a soft stop is especially valuable when measuring irregularly shaped or fragile items; it absorbs uneven contact points and prevents marring. This function combines with the jaws’ engineered contact geometry to maintain reliable grip without excessive clamping force. For workshops handling small series, prototypes or mixed-material assemblies, this balance safeguards components while preserving the integrity of measurement results and assembly operations.

The Vertex Universal Jaws VWSJ-R100 are compatible with calipers featuring a jaw width of 100–110 mm and are intended as a direct replacement set for such instruments. Will the soft stop prevent damage to delicate parts? Yes, the soft stop on the VWSJ-R100 reduces point loading on uneven surfaces, helping to protect delicate components while maintaining stable contact for measurements. How precise are measurements when using these jaws? When fitted and used on compatible calipers, the VWSJ-R100 supports repeatable contact with an accuracy of 0.01 mm, improving consistency across inspection cycles. Is the VWSJ-R100 suitable for high-volume workshop use? The compact design and reliable contact behaviour make the Vertex jaws suitable for frequent measurement tasks in production and inspection environments where quick jaw changes and consistent results are required. Can these jaws be used on calipers from other manufacturers? Compatibility depends on the caliper jaw width and mounting arrangement; the VWSJ-R100 is specified for 100–110 mm jaw width—confirm mechanical fit before installation.

Reduce set-up time and guarantee repeatable accuracy
Workpiece stops are essential mechanical positioning elements that provide a fixed physical reference for the exact, reproducible placement of blanks in machine tools or workholding. By referencing the blank against a predefined geometry the zero point for subsequent machining steps—milling, drilling or turning—remains identical from part to part, ensuring consistent dimensional accuracy in series production.
How they work and where they add value
In practice, a blank is simply pushed into contact with the stop and clamped; time-consuming manual alignment or repeated probing is eliminated. Variants include adjustable mechanical stops for changing geometries, quickly fixable magnetic stops for tool-free set-up, and precision-ground stop pins for fixture construction. Workpiece stops prevent unwanted slipping, rotation or axial movement during clamping and cutting, increasing process reliability across a wide range of workshop situations.
Key benefits for production
- Constant dimensional accuracy through a stable reference datum
- Reduced set-up time by removing repeated manual alignment and measuring steps
- Higher process reliability by preventing part movement during machining
- Faster changeovers with adjustable and magnetic variants
- Versatile compatibility with vices, chucks and bespoke fixtures

FAQ
What types of workpiece stops are available?
Workpiece stops are offered as adjustable mechanical stops, magnetic stops for rapid, tool-free fixation, and precision-ground stop pins for long-term fixture use.
How do workpiece stops reduce set-up time?
By providing a predefined reference geometry a blank can be pushed to contact and clamped directly, eliminating repeated manual alignment and time-consuming probing operations.
Can workpiece stops be used in turning operations?
Yes. Workpiece stops are used as internal spindle stops to define clamping depth in the chuck and as side stops on vises for milling setups, making them suitable for both turning and milling processes.
Are magnetic workpiece stops suitable for workshop use?
Magnetic stops are ideal for quick-change applications where tool-free reconfiguration is required; they provide fast fixation while supporting repeatable positioning when used on ferrous workholding surfaces.
