Square Bolt 304 Stainless Steel T-Bolt Hammer Head Screws Tugger

The square bolt enables an easier wrench grip for nut tightening. They are usually used in new construction to mimic an older aesthetic or in railway applications. Square head machine bolts were the industry standard prior to hex bolts gaining prominence. Square bolts are now most commonly used for aesthetic purposes to provide a rustic look in a new structure or to match existing fasteners in an older structure. Square lag screws are also used for these purposes. Ever Hardware provides the custom-made square bolt and customizable packaging.

Cross arm or machine bolts are commonly supplied for the utility industry and included an added cone point.
Ever Hardware manufactures square bolts from 1/2″ diameter through 2″ diameter in most ASTM, AASHTO, and SAE specifications. Special tooling can be created to produce nonstandard head dimensions or bolt heads with your company’s name and/or logo.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.
