Nuts and bolts are like salt and pepper

Nuts and bolts share the same chemistry as salt and pepper. Nuts are hardware fasteners with threaded holes. These holes are mated with bolts which help fastening a stack of different parts together. They are usually used in automobile, spare parts and for electrical usage. Nuts and bolts are strong, durable and dimension specific.

Nuts and bolts are graded with strength ratings, like an ISO property class 10 nut will be able to support the bolt proof strength load of an ISO property class 10.9 bolt without stripping. Likewise, an SAE class 5 nut can support the proof load of an SAE class 5 bolt, and so on. The proof strength of the most common property classes is listed at a bolted joint. Nuts and bolts are mostly hexagonal in shape as they give more strength and power through granularity of angles to a tool.

Common types of nuts and bolts include barrels, cap nuts, cage, coupling, crushed, cross dowel, inserts, internal wrenching, knurled nuts, lugs, panels, plates, flange,Hex Nuts, plate nuts, split nuts, weld nuts, staked, swage nuts, self-aligning nuts, Carriage Bolts. They can be used for various applications. Mostly made from low or medium carbon steel, with minimum tensile yield strength of 420 MPa or 61 ksi, nuts and bolts are ranked mostly in classes between 5 to 10.

Hex nuts, usually known as finished full are used for fastening to a bolt when mechanically joining materials together. Hex nuts are mostly made from materials like brass, zinc plates, steel grade 8, stainless steel, silicon bronze, hot dipped galvanized and grade 2 chrome. Hot dipped galvanized and grade 2 chrome are most popular hex nuts because of being corrosion resistant. They are thick and are used mostly for exteriors and coastal areas. Whereas, the grade 2 chrome has a bright mirror like finish providing sharp looks for a variety of applications.

Carriage bolts are usually used in wood works and have a domed top and a square under the head. Carriage bolts pull into the woods tightly and a recommended by hardware users for their safe and secure fits. Carriage bolts are also available in various metals like zinc, steel and bronze. Nuts and bolts generally used in applications that need hand tightening, and regular and heavy nutting. With a professional job, they can handle the load of the wood and doors that are hinged with them. Handled by a professional, they need no maintenance once they are fixed.
