## Description

Werder AG introduces the ultimate tool for mechanics. MechTab provides information about ISO-Tolerances, Threads, Cutting Data, Wrench Size and Roughness.

Tolerances: A - ZC, holes and shafts

General Tolerances: Charts for linear dimensions, radii/chamfer and angular dimensions.

Geometrical Tolerances: Symbols, drawings and explanations as well as charts for the different geometrical tolerances.

Threads: BA, BSF, G, Heli-Coil, M, MF, Pg, Tr, UNC, UNEF, UNF, W, Metric-Non-Standard

Cutting Data: Cutting Speed and Spindle Speed, Feed Rates, Processing duration

Wrench-Size to Width across Corners: 4-,6-8-,10-,12-,14-Cornered

Torque: 3.6, 6.9, 8.8, 10.9, 12.9

Roughness: Rz, Ra, N, Triangle-Notation

Weight: calculate the weight of different materials in different profiles. Material list is editable. 

Triangle: calculate sides, angles and the area of a triangle by entering 3 values according to a drawing.

Trowalisation: calculate the number of pieces
