Stud Bolt, Tap End and Double End Stud Bolts Stockist UAE

Stud Bolts:

The all-thread stud bolt is a fully threaded rod with 2 heavy hex nuts. Stud Bolt grades and sizes are well-defined by industry standards in ASTM A193 and ASME B16.5 standards.

Stud bolts known as studs are categorized into 3 basic types: Tap End Stud Bolts, Fully Threaded Stud Bolts, and Double End Stud Bolts.

Each of these have different engineering applications. Tap end studs have threads at extreme ends of the stud having unequal thread length, but double end stud bolts are differ in that they have equal thread length at both ends. Fully threaded studs are threaded fully across the body for full engagement of the mating’s nuts or similar parts. Apart from these there are stud bolts for flanges which are fully threaded studs with chamfered ends, and double end studs with reduced shank for special bolting applications.

We manufacture stud bolts across metric and imperial sizes. The stud bolts are offered in various material types such as carbon steel, stainless steel, high tensile steel, mild steel, Duplex, special alloys, aluminium and brass. We can produce bolts up to 6 inches in diameter and handle lengths over 4 feet on our state of art CNCs.

Engineering stud bolts (Double end studs): Manufacturing of Engineering Studs is our niche specially of bigger diameters and longer lengths. Our production of engineering studs gleams through with the High Temperature Material Grades and Super Duplex & special Stainless-Steel  Materials. We manufacture across standards such as BS 2693 BS 4439 DIN 525 DIN 938 DIN 939 DIN 940 BS 2693 BS 4439 NFE 25135

Collar bolts: are a type of fastener that is extensively used to hold the bundle in the exact place for removable bundle heat exchangers. This ensures the channel removal without interrupting or breaking the seal between the shell and tube sheet. At PMI we manufacture as per industry standards and customized as per customer drawings.
