Description
Stainless Steel Square Head Bolt — A2-70 (SS304) bolt for structural, machinery and general fastening. Complete with nut and washer on request. Stocked across common diameters and lengths in stainless and other finishes.
The stainless steel square head bolt combines a four-sided head with stainless corrosion resistance, suited to machinery, marine and industrial applications that need both a non-rounding, holdable head and permanent rust protection. The square head resists cam-out and can bear against a surface to prevent rotation, while the stainless grade keeps the fastener corrosion-free in wet, coastal or hygienic environments.
Stainless square head bolts are supplied in a range of diameters and lengths, in grades such as 304 and 316, with matching stainless nuts. Grade follows the environment. Confirm the sizes and grade in the specifications below.
