6 Adjustable Steel Parallel Blocks, 3/8 to 2-1/4 Inch Range for Precision Measurements

Welcome to our shop!

Discover our set of 6 adjustable parallel blocks, essential precision tools for all your machining and measuring work. Made of robust steel, these blocks offer exceptional reliability and durability.

Their main advantage lies in their adjustable feature. Thanks to a precise micrometer adjustment, you can set them to the exact dimension required, eliminating the need for multiple fixed parallel blocks of varying thicknesses. They are perfectly suited for checking the dimensions of grooves and holes, proving as useful as measuring gauges.

The design allows for smooth jaw movement, making adjustment both quick and easy.

To ensure a secure and stable hold, the smaller parallel blocks (models A, B, and C) are locked with a single screw, while the larger blocks (models D, E, and F) feature a reinforced locking mechanism with two screws. This set covers an extensive adjustment range, from 3/8 inch to 2-1/4 inches (approximately 9.5 mm to 57 mm), allowing for measurements over a wide range. **Specifications:** *Material:** Steel *Adjustment Range:** 3/8 inch ~ 2-1/4 inch **Package Contents:** You will receive a complete set of **6 adjustable parallel blocks**, ready to meet all your workshop needs.
