At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 2510 (all forms). Bolted connections with reduced-shank (waisted) studs for high-temperature / high-pressure flanged joints. This is an umbrella multi-part standard: DIN 2510-1 (general/overview), -2 (studs/double-end bolts with reduced shank, thread forms), plus associated nuts and sleeves. Forms cover the shank and end configurations (e.g. Form L / K reduced-shank studs, and the elongated nut and coupling elements). The reduced shank raises elastic resilience for thermal cycling. The table gives representative Form L reduced-shank stud geometry.
