(Machined components to customer specification / drawing also welcome)

Hot Forged Bolting

Hot Forged Bolting

Mellish Engineering Services Ltd Forging Department has heat inducted forge presses, which are capable of forging a wide range of diameters and lengths.

Most Nickel Alloys are forged at Mellish, along with all Duplexes and stainless steels. More common alloy grades of material are also forged. Hexagon and socket head components are what Mellish specialise in, but such is the diversity of special bolting, fasteners such as square head, 12 point (ferry heads) and cup square fasteners can also be produced.

Mellish also have a specialist tooling department based on site. Good quality tooling is vital in making sure you get the right quality fasteners on time, every time! This is why Mellish has invested into state-of-the-art spark erosion / toolroom equipment, which allows flexibility to produce hot forged fasteners on the quickest of deliveries.

Size Range: 3/8 (M10) – 1½ (M36)Hot Forged Bolting
Materials: All Carbon, Stainless, Nickel Alloy, Duplex grades of material (examples only)
Types: All head configurations, including Socket, Cup Square, Hexagon and Square Bolts
