Aspaton Pair of 123 Blocks Set – 1/10,000 Precision, 23 Holes, with Case

Overview

The Aspaton Pair of 123 Blocks Set delivers precision-focused performance for craft, prototyping, and fixture work. Each block measures 1 x 2 x 3 inches, offering a compact reference surface that supports repeatable setups. With a stated tolerance of 1 in 10,000, these blocks are designed to help you establish reliable reference points during busy days in the workshop or lab.

What’s included

• Two precision blocks with 23 holes per block
• Five hex screws and a hex wrench
• A sturdy carrying case for safe storage and transport

Key specifications and materials

• Material: high-quality steel for high hardness and wear resistance
• Size: each block 1 x 2 x 3 inches
• Precision: 1/10,000 total tolerance as specified
• Includes: two blocks, five screws, wrench, and case

Design highlights and benefits

In real-world setups, the 23-hole pattern provides flexible mounting positions, helping you reference multiple points during alignment. The solid steel construction resists deformation under routine usage, supporting durable, repeatable reference surfaces over time. The included screws and wrench simplify initial assembly and adjustments, so you can start work with minimal setup steps.

Applications and use cases

These blocks are well suited for fixture and jig work, alignment tasks for milling or drilling stations, inspection setups, and prototyping workflows. They’re designed to integrate into common bench workflows, offering a practical balance of size, precision, and ease of use.

How to use

1. Inspect surfaces and clean the blocks before use.
2. Place the blocks on the work surface and secure with screws as needed.
3. Align your workpiece against the holes to establish repeatable reference points.

Care and storage

Keep the set in the included case when not in use to protect against minor dings and moisture. Regularly wipe clean surfaces and remove debris to help maintain smooth operation over time.
