Precision 4CR13 Stainless Steel Vernier Caliper Tool

Product Overview:

Engineered for ultimate accuracy and longevity, our Premium Vernier Caliper is the perfect measuring tool for machinists, mechanics, engineers, and woodworkers. Crafted from premium 4CR13 stainless steel with a polished, matte chrome-plated finish, this precision caliper resists rust and glare while delivering smooth operation. Featuring high-frequency hardened measuring surfaces and a crisp laser-etched dual scale, it ensures reliable 4-way measurements for internal diameters, external diameters, depth, and steps.

Key Features:

Premium 4CR13 Stainless Steel & Matte Chrome Finish: Forged from high-grade 4CR13 stainless steel and treated with a satin, matte chrome plating, offering superior hardness, anti-corrosion resistance, and a non-glare surface for effortless reading.

High-Frequency Hardened Jaws: The measuring surfaces are fully induction-hardened to resist friction, wear, and deformation, ensuring long-term measurement accuracy and repeatability.

Laser-Etched Precision Scale: Clear, deeply laser-engraved graduations (Metric and Imperial) eliminate parallax errors and will never fade or wear off over time.

Versatile 4-Way Measurement: Easily measures external dimensions (outside jaws), internal dimensions (inside jaws), step dimensions, and depths (depth gauge rod) with high precision.

Smooth Slide & Thumb Lock: Fine-tuned sliding mechanism with an ergonomic thumb-locking screw allows quick adjustments and secure locking of the measurement for easy transfer.

Wide Applications (Scope of Use):

Machining & Metal Fabrication: Measuring shafts, bore diameters, metal parts, and lathe/milling workpieces.

Automotive & Mechanical Repair: Inspecting brake rotors, bearings, cylinder bores, and mechanical clearances.

Woodworking & DIY Crafting: Precision woodworking, 3D printing tolerance checking, and model making.

Quality Inspection & Laboratories: Industrial QC verification, educational laboratories, and aerospace component inspection.

FAQ:

Q1: What are the advantages of 4CR13 stainless steel over regular carbon steel calipers?

A: 4CR13 stainless steel offers significantly higher hardness, toughness, and corrosion resistance. Combined with the matte chrome plating, it will not rust from hand sweat or workshop humidity, and the non-glare surface prevents eye strain.

Q2: How does this vernier caliper achieve 4-way measurements?

A: It features external jaws for outer diameters, internal upper jaws for hole/slot diameters, a sliding depth rod at the tail for hole depths, and rear stepped faces for height/step measurements.

Q3: Will the laser-etched markings wear off after heavy daily use?

A: No. Unlike painted or printed markings, laser-etched graduations are permanently engraved into the metal, remaining crisp, clear, and abrasion-resistant throughout the tool's lifespan.

Q4: What is the MOQ and turnaround time for OEM custom branded orders?

A: The standard MOQ for custom laser branding and custom plastic cases is 1,000 pcs. The average mass production turnaround is 25–35 days upon sample and artwork confirmation.
