Stainless Steel Vernier Caliper 0-150mm – Precision Gauge

Achieve workshop-grade accuracy in your own hands with this Professional Stainless Steel Vernier Caliper. Whether you're a hobbyist, craftsperson, engineer, or home DIY enthusiast, this precision sliding gauge delivers reliable, repeatable measurements for a wide range of projects.

Key Features

• 4-in-1 Measurement Capability: Measures outer diameter (OD), inner diameter (ID), depth, and step — all in one compact tool.
• Precision Stainless Steel Construction: Hardened stainless steel build resists corrosion, warping, and everyday wear for long-lasting professional performance.
• Matte Chrome Non-Glare Scale: The graduated area features a matte chrome surface treatment that eliminates glare for clear, fatigue-free readings — even under bright workshop lighting.
• Engraved Scale Lines: Scale markings are precision-engraved (not ink-printed), ensuring the graduations never fade or smear with use.
• Locking Screw: A top-mounted locking screw holds your measurement firmly in place so you can record or reference readings without the jaw slipping.
• Smooth Sliding Action: The precision-fitted sliding jaw glides effortlessly along the main beam for fast, accurate positioning every time.
• Measurement Range: 0–150 mm (0–6 inches), covering the vast majority of everyday measuring tasks.
• Resolution: 0.02 mm vernier scale for fine, accurate readings.

Frequently Asked Questions

Q: What types of measurements can this stainless steel vernier caliper make?

A: This professional vernier caliper is designed to take four types of measurements: outer diameter (OD), inner diameter (ID), depth, and step measurements. The dual-jaw design and integrated depth rod allow you to tackle virtually any measuring task on a single tool, making it ideal for woodworking, metalworking, jewelry making, engineering, and general DIY projects.

Q: How do I read the vernier caliper scale accurately?

A: First, read the main scale (in mm or inches) to find the value just to the left of the vernier index line. Then look at the vernier scale to find which graduation aligns most precisely with a main scale line — this gives you the additional decimal value (0.02 mm resolution). The matte chrome, engraved scale on this caliper makes alignment easy to see without glare or fading.

Q: How does the locking screw work on this vernier caliper?

A: Once you've positioned the jaws around your workpiece and obtained your measurement, simply tighten the thumbscrew located on the top of the caliper. This locks the sliding jaw in position so the reading is preserved while you move the caliper away from the workpiece to record the dimension — very useful when working in tight spaces.

Q: Is this vernier caliper suitable for beginners as well as professionals?

A: Absolutely. The clear engraved scale, non-glare matte chrome finish, and smooth sliding action make this caliper easy to use for beginners, while the hardened stainless steel build, 0.02 mm resolution, and professional-grade construction satisfy the demands of experienced machinists, craftspeople, and engineers alike.

Q: How should I care for and store my stainless steel vernier caliper?

A: Wipe the jaws and beam clean with a soft, dry cloth after each use to remove dust or debris. Avoid exposing the caliper to moisture for prolonged periods. Store it in a protective case or pouch away from other metal tools that could scratch the scale. Periodically apply a very light coat of instrument oil to the sliding beam to maintain smooth action.
