# PartXT > An industrial parts, materials and standards database, organised in six modules: Parts, Materials, Standards, Applications, Tools and Knowledge. The fastener library is its first populated part family: nominal dimensions for screws, bolts, nuts, washers and rivets, drawn from DIN, ISO, ANSI and JIS standards, plus thread data, materials, property classes, standard comparisons and engineering calculators. Dimensions are nominal values in millimetres unless stated otherwise. They are compiled from published standards and are presented as factual reference data. Always verify against the current revision of the standard or the supplier drawing before ordering. ## Main sections - [PartXT — home](https://partxt.com/): Search parts, materials and standards — dimension tables for screws, bolts, nuts, washers and rivets across DIN, ISO and ANSI/ASME, plus calculators. - [Parts — Fasteners, Mechanical Parts & Hardware](https://partxt.com/parts/): The parts database: fasteners specified dimension by dimension against published standards, plus mechanical part families and the hardware still bein… - [Fastener specifications](https://partxt.com/parts/fasteners/): All 2538 fastener specification pages in 41 standards: screws, bolts, nuts, washers and rivets — nominal dimensions for every size. - [Mechanical Parts — Bearings, Gears, Springs & Couplings](https://partxt.com/parts/mechanical-parts/): Mechanical part families: rolling bearings, gears, springs, chain and belt drives, shafts, couplings and seals, plus the electrical and plumbing fami… - [Materials](https://partxt.com/materials/): Engineering materials with density and typical grades: steels, stainless, aluminium, rubbers, composites and common wood species. - [Standards index](https://partxt.com/standards/): Every standard on this site: 44 fastener standards (41 with dimension tables), 7 ISO bearing standards, 10 thread systems and the AS568 O-ring series. - [Thread Database — Metric, Unified, Pipe & Power](https://partxt.com/standards/threads/): Thread specs for ISO metric, UNC, UNF, UNEF, NPT, BSP and trapezoidal threads: pitch, TPI, major and minor diameter, thread angle and tap drill size. - [Applications — Materials, Fasteners & Tools Working Together](https://partxt.com/applications/): Twelve builds across furniture, construction and repair, each with its bill of materials: the material, the fastener standard and the tooling. - [Tools — Calculators and a Tool Reference](https://partxt.com/tools/): Calculators that answer from the database — tightening torque, material weight, thread identification — plus reference data on the tools that make th… - [Material Weight Calculator](https://partxt.com/tools/weight/): Calculate the weight of round, square, hexagon and flat bar and tube in steel, aluminium, plastics and wood, from section dimensions and density. - [Tightening Torque Calculator — Metric & Inch Bolts](https://partxt.com/tools/torque/): Tightening torque from thread geometry and property class, with friction treated as a control, not a footnote.
