Key Features of Moore and Wright Spring Callipers

Moore and Wright spring callipers incorporate several distinctive features that enhance their performance and longevity. The hardened and tempered steel construction provides excellent resistance to workshop wear whilst maintaining the rigidity essential for accurate measurement transfer. The precision-ground measuring faces ensure consistent contact with the workpiece, eliminating the measurement variations that can occur with poorly finished contact surfaces.

The spring mechanism itself is carefully engineered to provide firm, consistent tension across the entire measuring range. This prevents the common problem of calliper legs drifting during measurement transfer, which can introduce significant errors. The adjustment mechanism allows for smooth, controlled opening and closing, enabling users to achieve the precise fit required for accurate measurement work.

Each Moore and Wright spring calliper features a robust rivet joint that maintains alignment throughout the tool's working life. This attention to construction detail ensures that the measuring faces remain parallel, a critical requirement for obtaining reliable readings. The satin chrome finish provides corrosion resistance whilst reducing glare under workshop lighting conditions.

Popular Moore and Wright Spring Callipers

The Moore and Wright spring calliper range at Tooled-Up encompasses both outside and inside measuring variants across multiple size ranges. Outside spring callipers are the most commonly used type, ideal for measuring external dimensions such as shaft diameters, material thickness, and component widths. These are available in sizes ranging from 75mm up to 300mm capacity, accommodating the vast majority of workshop measurement requirements.

Inside spring callipers are specifically designed for measuring internal dimensions including bore diameters, slot widths, and recessed features. These tools feature outward-facing measuring points that allow access to internal surfaces, with size ranges matching their external measurement counterparts. Both types are frequently purchased in sets, providing comprehensive measurement capability across different size ranges whilst offering excellent value compared to individual purchases.

Divider-style spring callipers are also available within the Moore and Wright precision tool range, offering scribing and marking functionality alongside measurement transfer capabilities. These prove particularly valuable in layout work and pattern marking applications.

Safety and Compliance

Whilst spring callipers are relatively simple hand tools, proper usage techniques are essential for both measurement accuracy and personal safety. Moore and Wright spring callipers should be handled carefully to avoid damage to the precision-ground measuring faces, as impacts or dropping can affect measurement accuracy. When taking measurements, users should ensure adequate lighting and adopt comfortable working positions to avoid eye strain and repetitive strain injuries during extended measuring sessions.

The hardened steel construction means that measuring points can be sharp, particularly on inside callipers. Users should exercise caution when handling and storing these tools to prevent injury. Storage in dedicated tool rolls or compartmented boxes helps protect both the user and the measuring faces from damage.

Regular inspection of spring callipers ensures continued accuracy. Users should check for damage to measuring faces, weakness in spring tension, or looseness in the rivet joint. Moore and Wright recommends periodic checking against known reference standards to verify measurement accuracy, particularly for callipers used in quality-critical applications.

Frequently Asked Questions

How accurate are Moore and Wright spring callipers?

Spring callipers are transfer measurement tools rather than direct-reading instruments. When used correctly with an appropriate reference such as a steel rule or micrometer, Moore and Wright spring callipers can achieve accuracy within 0.5mm, making them suitable for general workshop applications. However, they are not precision instruments like micrometers or vernier callipers and should not be used where tolerances tighter than ±0.25mm are required.

What's the difference between inside and outside spring callipers?

Outside spring callipers have inward-facing measuring points designed for measuring external dimensions such as diameters and thicknesses. Inside spring callipers feature outward-facing points for measuring internal dimensions like bore diameters and slot widths. Moore and Wright manufactures both types to the same exacting standards, with the choice depending entirely on the measurement application.

How should I maintain my Moore and Wright spring callipers?

Keep the measuring faces clean and free from burrs or damage. Wipe down after use to remove swarf and moisture, then apply a light coating of oil to prevent corrosion. Store in a protective case or tool roll to prevent damage. Periodically check the rivet joint for tightness and ensure the spring tension remains firm and consistent throughout the movement range.

Can spring callipers be adjusted if they become loose?

Moore and Wright spring callipers are precision-manufactured tools with fixed rivet joints. If the joint becomes loose through wear or damage, it will affect measurement accuracy and reliability. Whilst some workshops attempt to tighten rivets, this risks damaging the alignment and spring characteristics. Replacement is generally more cost-effective than attempting repairs on worn callipers.

Are Moore and Wright spring callipers suitable for apprentice training?

Absolutely. Moore and Wright spring callipers are ideal training tools as they teach fundamental measurement transfer techniques and the importance of careful handling and proper measurement practice. Their durability ensures they withstand the learning environment, whilst their professional quality means apprentices train with the same standard of tools they'll use throughout their careers.
