Product details
Studbolts are made from long lengths of bars. We sell studbolts and nuts plain, Mastercote PTFE coated, Cadmium, Zinc Nickel Plated, Galvanised and other types of coatings. Electroless Nicklel plating is also available.
Mastercote fluropolymer coated bolts and nuts were developed to initially service the oil and gas companies in Malaysia. We work closley with them to derive a product that was both effective and cost efficent.
Mastercote bolting materials last much longer than any other fluropolymer coatings. Mastercote gives the best corrosion resistance, low friction with self-lubricating, non-galling properties - thus make-up and break out torques. It is excellent for offshore and subsea installations.
Mastercote resisits most acids and is unaffected even when exposed to hydrogen sulphide at 121 deg C at 2,000psi.
