FAQ – Frequently Asked Questions
-
What is the difference between a convex striking wrench and a standard striking wrench?
The convex head concentrates the striking force onto a smaller area, reducing the chance of the hammer slipping and providing better control compared to a flat face design. -
Can I use a hammer directly on the convex face?
Yes, the convex face is specifically designed to be struck with a hammer. We recommend using a steel or soft-faced hammer appropriate for the application. -
Is the 19mm opening suitable for both metric and inch fasteners?
19mm is a metric size closely matching 3/4 inch (19.05mm). It fits most 19mm hex fasteners, but for inch hardware, please verify tolerance. -
Do you offer custom lengths or opening sizes?
Yes, we can customize overall length, opening size, and surface finish according to your requirements. Minimum order quantities may apply. -
What kind of heat treatment does the wrench undergo?
Standard practice includes quenching and tempering to achieve a hardness of 38–45 HRC. Special heat treatment profiles can be arranged upon request. -
How do you ensure the wrench's durability under heavy impact?
Our 45# steel is carefully selected, and each wrench undergoes quality testing including dimensional checks and hardness verification. The convex geometry also helps distribute stress evenly. -
Can I get a sample before placing a large order?
Absolutely. We provide samples for evaluation. Please contact our sales team for sample pricing and lead time. -
What packaging options are available for bulk orders?
Standard packaging includes individual polybags or boxes, with customizable labeling and bulk carton packaging per customer specification.
