Industrial Grade V Blocks Set High Accuracy V Blocks for Toolroom Design Processing & Checking Work
Description:
V-Blocks are professional work holding fixtures that enable operators to securely locate and clamp workpieces for machining and inspection operations. The base, side faces and V contact surfaces are fully precision ground, offering stable, reliable and repeatable reference planes to guarantee consistent machining and measuring results.
To maintain long-term accuracy, V-Blocks require periodic inspection. Our V blocks are fully heat treated and precision machined, ensuring stable performance as dependable workshop holding tools.
The signature V-shaped dual contact surfaces firmly support components including round bar, tubular goods and shaft parts. Workpieces rest evenly against both faces of the V profile, which evenly distributes clamping pressure. This uniform force distribution locks the workpiece in a fixed position for precise milling, grinding, layout marking and runout testing.
Each matched-pair V Block is constructed from premium-grade steel, hardened to HRC 55–62 for superior wear resistance. Featuring a standard 90° V-angle and supplied with matching clamping brackets, our metric and inch specification V-blocks achieve high accuracy up to 0.005 mm (0.0002 inch).
Quick Detail:
1. Used for layout, machining and inspection jobs.
2. Made of high-quality steel and HRC55-62 hardness.
3. 90° V-Angles.

quality control in machinery & metrology labs.
Applications:
Precision steel V‑blocks with clamp are essential work‑holding fixtures widely deployed in machine shops,
CNC workshops, tool rooms and metrology laboratories. Benefiting from precision‑ground reference surfaces, standard
90° V‑angle and high‑hardness steel body, they deliver stable repeatable positioning for round bars, solid shafts,
tubular parts and cylindrical workpieces.
FAQ:
Q1: What are precision steel V‑blocks with clamp mainly used for?
A: These V‑blocks are professional work‑holding fixtures widely used for layout marking, machining and inspection jobs. They are ideal for shaft runout testing, grinding, milling, petroleum tubing inspection and quality control in machinery workshops and metrology labs. They securely hold round bars, tubular parts and shaft components during processing and measurement.
Q2: What material and hardness are your V‑blocks made of?
A: Manufactured from high‑quality premium steel, fully heat‑treated to hardness HRC 55‑62. High hardness brings excellent wear resistance, suitable for long‑term heavy‑duty workshop use.
Q3: What is the V‑angle of these V‑blocks?
A: Standard 90° V‑angle dual contact surfaces. The two V faces evenly distribute clamping pressure, keep round bars, shafts and tubes seated evenly for stable positioning.
