Parallel Blocks Set 23 Hole 0.0001 Precision Yunnergo

Description

Product Overview

The Yunnergo Ultra‑Precision Parallel Blocks are engineered for the most demanding dimensional calibration tasks. Each block measures 1 × 2 × 3 inches and features a network of 23 precisely drilled holes, each positioned with a tolerance of 0.0001 inch. Constructed from high‑quality hardened steel, the blocks resist wear, deformation, and corrosion, ensuring consistent performance over years of heavy use. The set includes a sturdy molded case and a full complement of screws, allowing users to secure the blocks in any fixture or jig without additional hardware. With a compact package size of 8.15 × 5.28 × 2.05 inches and a weight of just under 3 pounds, the system is portable enough for field service while still providing the rigidity required for laboratory‑grade measurements. Designed for compatibility with a wide range of measurement tools, the blocks integrate seamlessly with micrometers, dial indicators, and coordinate measuring machines, making them a versatile addition to any calibration toolkit.

Usage

These parallel blocks excel in environments where precision and repeatability are non‑negotiable. In a machine shop, technicians use the blocks to set up workpieces for grinding, milling, and drilling operations, guaranteeing that each axis remains perfectly parallel throughout the process. Woodworkers appreciate the ability to establish true reference planes for joinery, ensuring that mortise‑and‑tenon assemblies fit without gaps. In metal fabrication, the blocks serve as reference standards for verifying the accuracy of CNC machines and for calibrating inspection equipment such as height gauges and surface plates. The included case and screws simplify setup on workbenches, test rigs, and inspection stations, reducing downtime and eliminating the need for custom fixtures. Because the blocks are made from hardened steel, they maintain their geometry even after repeated clamping, making them ideal for high‑volume production lines and for occasional use in research laboratories where dimensional integrity is critical.
