Frequently Asked Questions
Q1: What is the material of this double box end wrench?
A: It is made from chrome vanadium steel (Cr-V), known for high strength and impact resistance.
Q2: Are the wrenches available individually or as a set?
A: Both options are available. Individual wrenches can be selected per size, and we also offer complete sets ranging from 6mm to 32mm in a pouch or rail.
Q3: Does the chrome plating peel off over time?
A: Our chrome plating is applied through a high-quality electroplating process that bonds tightly to the steel, providing long-lasting protection against corrosion and peeling under normal use.
Q4: What does DIN 838 standard mean?
A: DIN 838 specifies the dimensions, tolerances, and testing methods for double-ended ring wrenches with straight handles. Compliance ensures the wrench fits standard metric fasteners accurately.
Q5: Can I get custom size combinations on the same wrench?
A: Yes, we support OEM/ODM requests. You can specify which two sizes to combine, subject to minimum order quantity.
Q6: Are these wrenches suitable for high-torque applications?
A: Yes, the Cr-V steel construction and heat-treated strength allow them to withstand high torque without failure. However, for extremely high torque, we recommend using a longer handle or impact-rated tools.
Q7: Do you provide certification or test reports?
A: We can provide material test certificates and dimensional inspection reports upon request. Full compliance with DIN 838 can be documented.
Q8: What is the lead time for bulk orders?
A: For standard sizes, lead time is typically 15-30 days after deposit, depending on quantity. Custom orders may require 30-45 days.
