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.

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.
