Today, although the use of hex bolts are a prominent type of fasteners, its predecessor fastener was square shaped. Hence, it is not uncommon to see the use of Stainless Steel Square Head Bolts in older structures or buildings, or other engineering applications. The main benefit of using these 5/16 stainless steel square u bolts was that these fasteners were stable, with the odds of tool slippage being low. This is because, at angled corners, the square head machine bolts stainless steel would act as an anchor.

Available in various sizes and finishes, they are easy to install and any conventional tools may be suited to assemble a stainless steel cup square bolts system. Since most contractors could fix these fasteners with relative ease, the use of stainless steel square u bolts suit spaces that are either tight (space constraints) or dark and poorly lit. In such instances, most contractors have to fix the stainless steel square c bolts blind, without the availability of any visual markers.

Visual markers make it possible to screw, drill in, or fasten the most complicated fasteners. 316 stainless steel square u bolts, in comparison to grade 304 stainless steel are able to handle higher levels of weight and tension or stress, while also offering a significantly higher level of resistance to corrosion. In today’s times, it is typical to see the stainless steel square bolts being used for applications that demand a rustic appearance, especially in furniture or architecture based purposes.
