Frequently Asked Questions (FAQs)

# How Do I Measure a Bolt Correctly?

When measuring a bolt, you need to determine the diameter (D), the threads per inch (TPI), and the length under the head (L)?This is typically written as D-TP x L. For example, a ½” bolt with 13 threads per inch and 4” long would be written as ½-13 x 4..
# What Do the Marks on the Head of a Bolt Mean?

The marks on a bolt head identify the manufacturer and the material properties?For instance, “8.8” on a bolt head indicates it meets the ASTM A307 Grade A standard, and the manufacturer’s mark shows who made it..
# Do I Use the Same Size Wrench for the Nut and Bolt?

Yes, you use the same size wrench for the nut and bolt as long as they are of the same pattern (finish or heavy)?The width across the flats (WAF) of both the nut and bolt determines the wrench size..
# How Do I Determine the Necessary Torque for My Application?

To determine the necessary torque, you can use the Torque/Tension Equation: T = (K D P)/12?However, the best method is through experimentation under actual assembly conditions to ensure accurate results..
# Can I Get Certifications for My Parts?

Yes, you can request certifications for your parts?Manufacturers often keep these on file and can provide them upon request, usually for a small fee. Make sure to include the product description, size, and lot number in your request..
