Bolts are headed, externally threaded fasteners used to keep two objects, often metal or wood, in a fixed position relative to one another. Unlike screws, which cut their own threads, bolts pair with the internal threads of nuts to stay in place and ensure the desired level of tension in the bolted joint. The use of nuts aids in disassembly and reassembly. In addition, bolts generally have a greater load bearing capacity than screws but lack a tapered shaft. The head style of the bolt determines the tool required for tightening and loosening. Bolts are responsible for holding together everything from furniture to machinery to bridges.
Hex Head Cap Screws are designed for easy assembly into a tapped hole. Hex Cap Screws meet SAE specifications with a specially designed washer face under the head and a chamfered point. Grade 5 is the most common grade used in manufacturing assembly. Plain finish, or bare metal, will have a coating of light oil to resist corrosion. Tensile Strength: 120,000 psi minimum.
