Bolts and Nuts

BOLTS AND NUTS

A Steel Bolt is a mechanical fastener that is usually used with a nut for connecting two or more parts. A bolted joint can be readily disassembled and reassembled; for this reason bolts or screw fasteners are used to a greater extent than any other type of mechanical fastener and have played an important part in the development of mass-produced articles and steel structures.

The bolt consists of a head and a cylindrical body with screw threads along a portion of its length. The nut is the female member of the pair, having internal threads to match those of the bolt. Washers are often used to prevent loosening and crushing. 

Common Bolt Types used in the Market:

  • Anchor Bolt– Bolt designed to allow objects to be attached to concrete. The bolt head is usually placed in concrete before it has cured or placed before the concrete is poured, leaving the threaded end exposed.
  • Hex Boltor Machine Bolt – Bolt with a hexagonal head and threaded body. Section immediately under head may or may not be threaded.
  • J bolt– Bolt shaped like the letter J. Used for tie downs. Only the non-curved section is threaded for a nut to be attached.
  • U Bolt– Bolt shaped like the letter U where the two straight sections are threaded. A straight metal plate with two bolt holes is used with nuts to hold pipes or other round objects to the U-bolt.
  • Stud Bolt– a bolt with threads on both ends designed to be screwed permanently into a fixed part at one end and to receive a nut on the other.
