Shars Grade Economy 81 PCS Rectangular Gage Block Set with NIST traceable certificate 303-5311C M

Description

Product Overview

The Shars Grade Economy 81‑piece rectangular gage block set is engineered to meet the rigorous demands of modern dimensional calibration. Each block is manufactured from hardened tool steel, providing exceptional wear resistance and long‑term stability. The set includes a comprehensive range of sizes: nine blocks covering .1001″ to .1009″ in .0001″ increments, forty‑nine blocks from .101″ to .149″ in .001″ steps, nineteen blocks from .050″ to .950″ in .050″ steps, and four larger blocks ranging from 1″ to 4″ in 1″ increments. Every piece is NIST‑traceable, accompanied by a certificate that guarantees the accuracy of each dimension within the specified tolerance. The compact packaging measures 13.39 x 11.46 x 4.37 inches and weighs 7.01 pounds, making it easy to store and transport while protecting the precision components inside.

Usage

This gage block set is ideal for a variety of precision environments, including machine shops, calibration laboratories, quality‑control departments, and educational institutions. Technicians use the blocks to verify the accuracy of CNC machines, coordinate‑measuring machines (CMMs), micrometers, and other measurement tools. The rectangular geometry allows for easy stacking and alignment, facilitating quick setup for routine checks or detailed calibration procedures. Because the set spans from .1001″ to 4″, it supports both fine‑tuned adjustments for high‑precision components and larger scale verifications for heavy‑duty equipment. The NIST‑traceable certification gives confidence to engineers and auditors that the measurements conform to internationally recognized standards, reducing the risk of costly rework or non‑compliance penalties.

FAQ

What does NIST‑traceable mean for this gage block set?

NIST‑traceable indicates that the dimensions of each block have been calibrated against standards maintained by the National Institute of Standards and Technology. This traceability ensures that measurements taken with the blocks are consistent with internationally recognized accuracy levels.

Can these blocks be used for both metric and imperial measurements?

Yes. While the set is listed in imperial inches, the precise increments can be easily converted to metric values, allowing the blocks to serve dual‑purpose calibration needs in environments that require both measurement systems.

How should the blocks be stored to maintain their accuracy?

Store the blocks in a clean, dry environment away from temperature extremes and magnetic fields. The original packaging provides a protective case, but for long‑term storage, a dedicated metrology cabinet with a controlled humidity level is recommended.

Is the set suitable for calibrating CNC machine tools?

Absolutely. The fine‑step blocks (.1001″ to .1009″) are perfect for verifying the precision of spindle positioning, while the larger blocks (1″ to 4″) can be used to check overall machine geometry and alignment.

What warranty or after‑sales service does Shars provide?

Shars offers a one‑year limited warranty covering manufacturing defects, along with a responsive technical support team that can assist with calibration questions, replacement parts, or documentation needs.
