Product Description

A4 stainless steel bolts (Set-Screws) in 316-grade stainless steel.  Because these stainless steel bolts are fully threaded they are, strictly speaking, called set-screws.  The head is stamped with the A4-70 grade of stainless steel used.  The A4-70 grade represents a tensile strength of 700 Newtons per square mm, similar to a standard high-strength steel bolt, but not as high as the highest steel bolt grades.  

These A4 stainless steel bolts are suitable for general structural applications where resistance to corrosion and staining is needed.  Use A4 stainless fixings for boats and marine equipment for the best corrosion resistance.  A4-stainless fixings are commonly used in and around boat engine bays, for boat trailers, dock equipment, and many other uses.

See our 'Thread And Bolt Selection' guide for further information on set-screw or bolt threads and length definitions.  Also, see our 'Stainless Steel Material Guide' for a discussion of A2 vs A4 stainless steel grades.

In addition to these hexagon-head set-screws, we also stock cap-head and countersunk bolts.  Use these A4 stainless steel bolts with our washers and nuts depending on your sailing or other marine application.
