Description

Conquest 5/8" x 2-1/2" Carriage Bolt - 316 Stainless Steel

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

The Conquest 5/8" Carriage Bolt made from premium 316 stainless steel is built for the most demanding environments. Its resistance to rust, chemicals, and saltwater exposure makes it the ideal fastener for marine, coastal, and industrial use.

5/8" Conquest 316 Stainless Steel Carriage Bolt – Marine-Grade Corrosion Resistance

With a smooth domed head and square neck, this bolt ensures clean aesthetics and secure grip during installation. Commonly used in structural, decorative, and heavy-duty applications where strength and corrosion resistance are essential.

  • Thread Type: Coarse
  • Threads Per Inch (TPI): 11
  • Material: 316 Stainless Steel for extreme corrosion protection
  • Head Type: Round head with square neck to prevent spinning

Had the fasteners

Had a little trouble getting through the first step. The size i was looking for didn't show up, but I clicked on a simular bolt which takes you the real menu. Then I was able to put in all the specs and found exactly what I was looking for. Don't give up if your first search doesn't display the part you want.

The shipment arrived and is in great shape. However, it was delayed, which is fine, but after three notices of ‘your delivery will be there tomorrow’ I had no confidence and was annoyed with the updates.
