Quality Lab

Laser Lead Measurement

Precise lead error gauging is utilized to validate processes to Nook internal specifications and customer requirements.

Zeiss Roundness and Contour Measurement

Critical to quality, characteristics such as roundness are monitored throughout the screw manufacturing process. Prior to the start of any production run, thread form geometry is precisely measured to stringent engineering specifications.


The metallurgical lab is capable of determining material composition from raw materials to final product. A micro hardness and case depth inspection is a routine check that validates the heat treat process.

Functional Testing

Functional Testing

Nook test systems and engineered testing processes perform analysis, verification, and solidification of life, durability, and performance. The functional testing defines operating limits in specifications and helps set defined targets in Product Launch Process and Assurance Plans. This provides predictive tools, generates data for prognostics, and validates performance wear models. Life tests help determine performance in multiple operating conditions as well. Nook offers proof testing for customers developing new systems and actuators to help accelerate product release dates.

Nook Engineering has designed test machines to measure and validate screw assembly efficiency. Preloaded ball screw assemblies are evaluated to determine compliance with engineering specifications utilizing a Dynamic Torque Testing Machine.
