Fastener Engineering Toolbox
Practical engineering references and calculators trusted by our engineers — data sheets, cross-referencing, weights, BOQ packing lists, torque, flange bolting and plating/head-stamp identification for industrial fasteners.
Data Sheets & CAD
Browse fastener standards (DIN / ISO / ASTM / ASME) with dimensional specs, CAD blueprint schematics, drilling & clearance data, and chemical composition.
Open Tool →Cross-Reference Tool
Match DIN, ISO, ASME, BS, JIS and EN standards, plus manufacturer part numbers, to find the exact functional equivalent fastener.
Open Tool →Weight Matrix
Theoretical weight chart by diameter × length, with material density multipliers for alloy steel, stainless, duplex, Inconel, Monel and titanium.
Open Tool →Calculator & BOQ
Calculate single or bolted-set weights and build a consignment packing list / bill of quantities with carton and pallet estimates. Export to CSV.
Open Tool →Torque & Tension
ISO 898-1 / VDI 2230 tightening torque and clamping force tables with an interactive friction-adjusted torque calculator.
Open Tool →Flange Bolting (B16.5)
ASME B16.5 flange bolting reference — stud diameters, lengths, bolt counts and wrench sizes for 150# to 1500# flanges.
Open Tool →Platings & Head Stamps
Surface coating specifications, hydrogen embrittlement guidance, and a head-stamp decoder for material grade identification markings.
