Frequently Asked Questions (FAQ)

What wrench size is used for a 1/2" hex bolt head?

A bolt with a 1 2 hex bolt head size (measured across the flats) requires a standard 3/4-inch (19mm) wrench or socket for installation and removal.

Are these bolts suitable for outdoor or marine environments?

Yes, when specified with the appropriate material and finish. We recommend stainless steel (A4-80 for marine) or carbon steel with a hot-dip galvanized finish for superior corrosion resistance in harsh conditions.

What is the difference between Grade 5 and Grade 8 hex bolts?

Grade 8 bolts are made from medium carbon alloy steel and are heat-treated for higher tensile and yield strength (minimum 150 ksi tensile) compared to Grade 5 (minimum 120 ksi). Grade 8 is used for the most demanding, high-stress applications.

Can I order samples before placing a bulk order?

Absolutely. We encourage potential clients to evaluate our product quality. Contact our sales team to request sample kits of our 1/2 inch hex bolt head size products in your specified grade and finish.

Do you provide certification with the bolts?

Yes. We can supply Mill Test Certificates (MTCs) or Certificates of Conformance (CoC) with shipments, detailing the chemical composition and mechanical properties of the material, as required for quality audits and project specifications.
