What is a Collar Bolt?
Collar Bolts shall have a square extension beyond the threads for use of a wrench to prevent turning of the bolt when the nuts are tightened or removed. A Collar bolt is a form of threaded hardware device with an external male thread. Bolts are thus closely related to, and often confused with, screws. Set collars bolts are used for removable bundle heat exchanges, to holding the bundle in place, if only the channel must be removed. Collar bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. A bolt is a form of threaded fastener with an external male thread. Bolts are closely related to screws.
Inspection & Testing of Collar Bolts
- Mechanical Testing Such as Tensile of Area, Hardness Test, Positive Material Identification – PMI Testing, Flattening Test, Micro and Macro Test, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test.
