7. FAQ

Q: What is the difference between a hex bolt and a hex cap screw?

A: In modern usage, the terms are often used interchangeably for fasteners with a hex head and a threaded shank. Technically, a "cap screw" is designed to be used in a tapped hole without a nut, while a "bolt" is intended for use with a nut. Our 1 4 x 1 2 hex bolt can function as either.

Q: What grade of steel is recommended for general-purpose use?

A: For most industrial applications, Grade 5 (medium carbon steel) with a zinc-plated finish offers an excellent combination of strength, durability, and corrosion resistance at a competitive price point.

Q: Is the 1/2" length measured from under the head or including the head?

A: For hex bolts and cap screws, the nominal length (1/2") is measured from the underside of the head to the very end of the bolt. The height of the head is not included in this measurement.

Q: Can I get this bolt in a stainless steel material?

A: Absolutely. We supply this size in A2 (304) stainless steel for general corrosion resistance and A4 (316) stainless steel for superior resistance in harsh environments, including exposure to chemicals and saltwater.

Q: What is the minimum order quantity (MOQ) for this product?

A: We cater to businesses of all sizes. We offer flexible MOQs, with competitive pricing tiers for sample orders, small cases, and large bulk purchases. Contact our sales team for a specific quote tailored to your volume needs.
