Square head bolts used to be the go-to builts in almost any application back then. This is because it offers a large bearing area for gripping. Besides, their shapes make them easy to manufacture. This was particularly beneficial back in those days when machines were rare. These days, square bolt heads are still used, albeit rarely, when the application requires a maximum amount of torque and for aesthetic purposes. It provides that rustic look and matches fasteners in old structures.

However, because square head bolts require more twist to fasten, hex bolts replaced them. This is especially true for tight spaces where the application requires “good granularity of angles for a tool to approach from.”

304 Stainless Steel is the material used for this bolt. Type 304 Stainless steel is a T300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. Knowing this, you may be confident that your 304 stainless steel stove bolt is corrosion-resistant.
