SQUARE BOLT

Squarehead bolts are also called machine screws.  These can be used with appliances and electronics and special requirements. The head design of square bolts enables an easier wrench grip for nut tightening. These are used in new construction to mimic an older one. Square Bolt, the grade 5 bolts are more than Grade 8, allowing them to better withstand shear force. These bolts feature a square head design for use in heavy-duty applications. Square Head Bolts are the UNC equivalent of Metric Class 8.8 Steel Square Head Bolts. The design of these bolts enables an easier wrench grip for nut tightening. They are usually used in new construction along with the square plate.

Square bolts are also used to match existing fasteners of grown-up structures. SEF manufactures high-quality square bolt fasteners.

Squarehead machine bolts were the industry standard before hex bolts gained prominence Square bolts are now most commonly used for purposes to provide a rustic look in a new structure or to match existing fasteners in an older structure. Even the Square lag screws are also used for these purposes. Crossarm or machine bolts are commonly supplied for the utility industry and included an added cone point.
