Metline can supply titanium pipes, titanium fittings, titanium flanges, gaskets and titanium fasteners, nuts & bolts required for any type of piping fabrication project.

We specialise in the supply of Titanium Fasteners in Grade 1, Grade 2, Grade 3, Grade 5, Grade 7, Grade 9, Grade 12, Grade 16 titanium and its alloys. Titanium and Titanium Alloy Fasteners find application in various industries such as pulp and paper industry, water and seawater service, chemical processes involving oxidizing media and oxidizing acids. In addition to Titanium Fasteners, Metline also produces Monel Fasteners, Inconel Fasteners and Hastelloy Fasteners.

Titanium alloy fasteners provide a high strength-to-weight ratio, while bridging the gap between the properties of steel and aluminum. Titanium Grade 5 (Ti-6A14V) fasteners are popular in the industry of racing motorcycle and cars for its high tensile strength and lightness, it is mainly used in racing car, motorcycle and bike application. Titanium Grade 2 (Pure titanium) fasteners are mainly used in petrol, chemistry and oil field industry for its corrosion resistance property.

Titanium Bolts Manufacturing & Supply Range

A Bolt is a device with a head on one end of a shank or body and a thread on the other end. Designed for insertion through holes in assembly parts, it is mated with a tapped nut. Tension is normally induced in the bolt to compress the assembly by rotating the nut. This may also be done by rotation of the bolt head. Bolts are generally considered to be larger than screws and are used in a wide variety of applications especially where load-carrying capacity is a requirement.

Types of Titanium Bolts – Button Head Socket Bolts, Carriage Bolts, Elevator Bolts, Flat Head Socket Bolts, Hex Head Bolts, Hex Flange Bolts, Hex Lag Bolts, Low Head Socket Bolts, Pilot Recess Socket Bolts, Shoulder Bolts, Sidewalk Bolts, Socket Head Bolts, T-Bolts, U-Bolts, J-Bolts

Titanium Threaded Rods/Stud Bolts Manufacturing & Supply Range

A Stud is a fastener with no head but it has threads at both ends of the shank. It, like a screw, has one end that screws into a tapped hole. A nut is used on the other end to create tension. If a stud is threaded its entire shank length and a nut used on both ends to create tension, it serves the function of a bolt and is then classified as a Stud Bolt.

Type of Titanium Threaded Rods or Stud Bolts: Double Ended Rods, Full Threaded Rods, Double Ended Studs, Full Threaded Studs

Titanium Washers Manufacturing & Supply Range

In general, washers are used to increase the bearing surface of a nut or fastener’s head, provide a smooth mating surface or protect the surface from damage when the nut or head is rotated, compensate for oversized or irregular shaped holes, space or shim parts, or to resist loosening. Washer size refers to its nominal hole size and is based on screw size.

Types of Titanium Washers: Plain/Flat Washers, Split Lock Washers, Fender Washers, External Tooth Lock Washers, Internal Tooth Lock Washers, Finish Washers, Flange Finish Washers, Special Washers, Square Washers

Titanium Screws Manufacturing & Supply Range

A Screw is a headed and threaded bolt used without a nut. It is inserted into an internally tapped hole and tension is induced by rotation of the screw head.
