Studbolts

Studbolts are made from long length of bars. We sell studbolts and nuts plain, Mastercote PTFE coated, Cadmium, Zinc Nickel Plated, Galvanised and other types of coatings. Electroless Nickel plating is also available.

Mastercote® fluoropolymer coated bolts and nuts were developed by us to initially service the oil and gas companies in Malaysia. We worked closely with them to derive a product that was both effective and cost efficient.

Mastercote® coating is effective and more economical than using stainless, incoloy, titanium and dother exotic materials.

Mastercote® bolting materials last much longer than any other fluoropolymer coatings. Mastercote® gives the best corrosion resistance, low friction with self-lubricating, non-galling properties – thus reducing make-up and break out torques. It is excellent for offshore and subsea installations.

Mastercote® resists most acids and is unaffected even when exposed to hydrogen sulphide at 121ºC at 2,000psi.
