ZEPHYR PART NUMBERS-
your guide to quality and hardness

Only Zephyr of all major screwdriver bit manufacturers gives you a complete part number on the bit to assure that you have the right bit you need for the job.

Use “X” grade for hard sheet metal screws and fasteners. “A” grade is recommended for machine screws.

‘I’ Intermediate hardness is also available on order.

All Zephyr bits are heat treated in small lots for consistent quality. Zephyr’s unique Z-ForgeTM process assures exact dimensional fit in the recess. A Zephyr bit gives the truest fit, longest performance and with our new ACR® bits, the least cam-out and product damage of any available at any price.

Made in U.S.A.

Every Zephyr bit proudly wears this mark. We assure you that we will always supply the finest product engineered to last.

Safety Counts

Zephyr products are designed to be safe under proper working conditions. Be sure that you know the proper way to use a tool before working with it. We recommend the wearing of eye protection when using any hand tool or machine shop tool.

Keep your tools clean, inspect them from time to time, and replace worn or damaged tools. The nominal cost will be more than offset by the reduction in mistakes and the savings on rework.
