RS PRO Steel Metric Gauge Block Set, 47 Piece, Heat Treated with UKAS 5 Point Calibration Certificate 409-2312

RS PRO 409-2312 is a precision steel metric gauge block set consisting of 47 individual gauge blocks providing accurate measurement capabilities essential for calibration and machining tasks. Manufactured from high-quality steel that has undergone heat treatment certified to HRC65/HV820, these blocks offer durability and hardness necessary for maintaining measurement integrity over repeated use.

The gauge blocks feature an ultra-micro lapped surface finish, resulting in impeccably flat and smooth surfaces needed for wringing - a technique that allows blocks to be combined without gaps ensuring exact distances between surfaces. These blocks come housed in a fitted wooden case offering protection and organized storage.

This set includes a UKAS 5 point calibration certificate, providing traceable verification of accuracy compliant with EN and ISO standards. The 47 different sizes in the set cover ranges from 1.005 mm to 100 mm across several graduated pieces: one block at 1.005 mm, twenty blocks ranging 1.01 to 1.20 mm, seven blocks from 1.30 to 1.90 mm, nine blocks from 1.0 to 9.0 mm, and ten blocks spanning 10.0 to 100.0 mm.

RS PRO gauge blocks are used extensively in industrial environments including engineering workshops, laboratories, manufacturing facilities, and construction sites where precise calibration of measuring tools and fine machining accuracy is critical. The set facilitates both individual and combined measurements for a wide array of dimensional inspection and tooling tasks.

The set includes 47 gauge blocks for a broad range of accurate measurement. Blocks are made of high-quality steel with heat treatment for hardness and durability. Ultra-micro lapped surfaces ensure an ultra-smooth and flat finish for perfect wringing.

Supplied in a fitted wooden case for safe storage and transport. Each set includes a UKAS 5 point calibration certificate for verified accuracy. Suitable for calibration of engineering equipment and precision measuring instruments.

Commonly used in manufacturing, construction, and fine machining applications. Choose this RS PRO Gauge Block Set for reliable, certified dimensional calibration, perfectly suited for various industrial and engineering measurement applications.
