What bolts to use with flanges?
The most common materials for stud bolts (for flanges) are ASTM A193 (grade B7, B8, B8M, B8T), ASTM A453 (grade 660), ASTM A320 (grade L7, L7M), and ASTM A182 (duplex and super duplex bolting). For aggressive fluids and environments, stud bolts can be coated with Xylan, Xylar and other materials.
What are connector bolts used for?
Typical uses of connector bolts include the assembly of cabinetry and knock-down furniture. The fastener head is thin with a large diameter and normally has a hex recess for driving in pre-drilled holes.
What is the difference between rivet and bolt?
1. A bolt acts like a screw and has male threads, a rivet consists of a smooth cylindrical shaft with a head on one end, with no threads. 2. A bolt easy to put together and take apart, a rivet likes a metal stick holding two pieces of metal together, the only way to take it out is to cut or drill it out.
What are the different types of LRFD bolts?
a) High-Strength Bolts: The three basic types of high strength listed in the LRFD are: ASTM designations A325, F1852, and A-490. The new ASTM specification F1852 refers to the fasteners frequently referred to as tension control, TC, twist-off, or torque-and-snap fasteners. High-Strength bolts range in diameter from ½ to 1 ½ in.
What are the markings on a bolt fastener?

What kind of bolts are used in light structures?
They are sometimes referred as common, machine, or rough bolts. These bolts are used primarily in light structures, secondary or bracing members, platforms, catwalks, purlins, girts, light trusses, and other structures with small loads and static in nature. The A307 bolts are used predominantly in connections for wood structures. c) Rivets
What do you need to know about bed bolts?
Learn more… Bed bolts are long screws that hold the pieces of your bed frame together. The way you secure your bed bolts may vary depending on the type of frame you have. Some bed frames have circular holes and use barrel nuts, while others only use washers and nuts to hold the bolt in place.
What kind of bolts are used for lag bolts?
Hex Bolts Carriage Bolts Lag Bolts Bolts with a hexagonal head with threads for use with a nut or tapped hole. Abbrevi- ated HHMB or HXBT. Bolts with a smooth rounded head that has a small square section underneath. Plow Bolts Similar to carriage bolts but used for attaching the cutting edge of a plow to the plow blade.

Which is the best specification for structural bolts?
• The Research Council on Structural Connections (RCSC) prepares specifications and documents related to structuralconnections • RCSC’s Specification for Structural Joints Using ASTM A325 or A490 Bolts (2000) is a widely used specification which discusses joints, fasteners, limit states, installation, and inspections.
Can a tensioned bolt return to its original shape?
Thus, a bolt that is properly tensioned should be functioning in the elastic range (as viewed on the Diagram). If the load is removed and the fastener is still within the elastic range, the fastener will always return to its original shape. However, if the load applied causes the fastener to exceed its yield point , it enters the plastic range .
