Engineers Studs
We manufacture precision-engineered studs to metric and imperial standards in various materials including stainless steel and high tensile grades. Our BS1083 and BS4439-compliant products suit critical applications across multiple industries. With in-house CNC capabilities, we maintain tight tolerances while offering same-day dispatch for standard items.
Shaft Collars
Our metric and imperial shaft collars meet BS4185 specifications in solid, single-split, and double-split configurations. Available in EN1A steel, stainless steel, and aluminium, these components support mechanical assemblies requiring precise positioning and torque transmission in industrial machinery applications.
Gib Head Keys
Manufactured to BS46 and BS4235 standards, our gib head keys feature 1:100 taper precision for secure shaft-hub engagement. Produced in EN8 steel and stainless grades, these components eliminate backlash while enabling tool-free installation and removal for maintenance efficiency.
Safety Valves
Dereve-branded safety valves include fusible plugs and pressure relief systems compliant with EU directives. Our engineered solutions ensure system integrity in boiler installations and industrial equipment through precision-machined components with stress corrosion-resistant materials.
Precision Turned Parts
Custom precision-turned components produced using modern CNC machining alongside traditional methods. We support low-volume prototypes to high-volume production runs in exotic alloys and non-ferrous metals, maintaining tolerances for aerospace, automotive, and specialist engineering sectors.
