Direct Shear Stress Calculator
Average shear on pins, rivets and glue lines — single or double shear.
Double shear halves the stress for free — why clevises beat lap joints. Allowable shear ≈ 0.58× tensile yield (von Mises) for ductile metals.
Formula
Direct Shear Stress Calculator is a free shear stress pin for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Direct Shear Stress Calculator
Average shear on pins, rivets and glue lines — single or double shear. The calculation implements τ = P/(n·A) (Machine design — pinned joints). Double shear halves the stress for free — why clevises beat lap joints. Allowable shear ≈ 0.58× tensile yield (von Mises) for ductile metals.

Frequently asked questions
What formula does the Direct Shear Stress Calculator use?+
It computes τ = P/(n·A), per Machine design — pinned joints. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Double shear halves the stress for free — why clevises beat lap joints. Allowable shear ≈ 0.58× tensile yield (von Mises) for ductile metals.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Direct Shear Stress Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
