Product Description

Stainless steel offers excellent protection against deterioration and corrosion but has caveats to be aware of.

The tensile strength of type 316 stainless steel is only slightly stronger than un-hardened grade 2 ferrous steel; for specific tensile strengths, please refer to the chart in the image carousel.

Be aware that when combining stainless steel fasteners; especially stainless lock nuts regardless the thread type or bolt diameter, it's recommended to coat the male bolt threads in never-seez before assembly as galling can occur and cause the nut to fuse to the bolt during installation/disassembly, leaving the threads looking melted as the nut seizes in place and any further turning of the wrench just shears the bolt in half.

To correctly measure the length "L" of any hexagon head cap screw, you must measure under the head.

When selecting inch threads, thread pitch is measured by counting every thread contained within 1" and is spoken as "threads per inch" (i.e. 3/8"-16 TPI)

When selecting metric threads, thread pitch is measured from one thread peak to the next in millimeters (i.e. M10-1.25mm). Many metric threaded bolts are cut with fine and extra-fine threads which further necessitate the need for proper thread identification before ordering. Vernier calipers and thread gauges proove invaluable for this task.
