Radius Gauge 4‑Piece Stainless Steel Set Rustark R0.3‑25

Description

Product Overview

The Rustark 4‑piece radius gauge set is engineered for precision measurement of both internal and external radii across a broad spectrum of sizes. Constructed from high‑grade stainless steel, each gauge resists corrosion, wear, and deformation, ensuring long‑term accuracy even in demanding industrial environments. The set includes four gauges covering the ranges R0.3‑1.5, R1‑6.5, R7‑14.5, and R15‑25, providing a seamless transition from fine fillet work to larger radius applications. Each leaf features laser‑engraved scale markings that are easy to read at a glance, eliminating guesswork and reducing setup time. The 360‑degree locking screw mechanism allows the gauges to be quickly unfolded for use or folded compactly for storage, delivering both convenience and safety during handling. With a compact package measuring 7 × 3.9 × 1.3 inches and weighing just one pound, the set is portable enough for field service while still offering the robustness required on the shop floor.

Usage

These gauges are versatile tools suitable for a wide range of industries and applications. Mechanical engineers rely on them to verify the radii of machined components such as valve seats, bearing housings, and turbine blades. Electric contractors use the gauges to check the curvature of conduit bends and cable trays, ensuring compliance with code‑mandated tolerances. In the automotive sector, technicians employ the gauges to inspect the fillet radii of engine blocks, suspension brackets, and chassis welds, helping to prevent stress concentrations that could lead to premature failure. Hobbyists and DIY enthusiasts also benefit from the set when working on home improvement projects, such as fitting custom handrails, fabricating furniture joints, or aligning decorative metalwork. The dual‑blade design on each gauge provides a convex side for measuring outward curves and a concave side for inward curves, making the tool adaptable to any geometry encountered on the job.

FAQ

What materials can be measured with these radius gauges?

The gauges are suitable for measuring radii on metal, plastic, wood, and composite materials. Their stainless steel blades maintain sharpness and accuracy across a variety of surface finishes, making them ideal for both hardened steel components and softer substrates.

How do I maintain the gauges to ensure long‑term accuracy?

After each use, wipe the blades with a clean, dry cloth to remove debris and moisture. Store the gauges in the supplied case to protect them from impact. Periodically inspect the laser‑engraved markings for wear; if the markings become illegible, contact Rustark customer service for calibration assistance.

Can the gauges be used for both internal and external radius measurements?

Yes. Each gauge features a dual‑blade configuration: one side is convex for measuring outward curves, while the opposite side is concave for measuring inward curves. This design allows a single gauge to handle both types of measurements without the need for separate tools.

Is the set compatible with metric and imperial measurement systems?

The gauges are calibrated in metric units (millimeters) as indicated by the laser‑engraved scale. For users who require imperial measurements, a conversion chart can be applied, or a separate conversion tool can be used alongside the set.

What is the recommended temperature range for using these gauges?

The stainless steel construction performs reliably from -20 °C to 120 °C (-4 °F to 248 °F). Operating outside this range may affect material properties and measurement accuracy, so it is advisable to use the gauges within the specified temperature limits.
