Pin + Clevis Joint Calculator.
Screen single- or double-shear pin joints for average pin shear, projected bearing stress, and governing material margin.
Pin + clevis joint / average shear and bearing
Live calculationτ = F / (nA); σᵦ = F / (td)Pin-joint results updated. Pin average shear 63.66 megapascals. Governing factor of safety 2.
- F: applied load
- d: pin diameter
- t: lug thickness
- n: shear planes
- S: material allowable
- 10 kN double shear: 125 MPa lug bearing and FoS 2.0
- Invalid plane count: input is rejected
Added visible variables, two verification examples, and an experience connection. Calculation method is unchanged.

This model is a fast load-path screen for the pin, central lug, and clevis ears. It helps identify the element that deserves the next geometry or allowable iteration.
Detailed design must add pin bending, net-section and shear-out failure, edge distance, clearance, eccentricity, fatigue, wear, retention, and local contact behavior.
Before releasing the joint
- Check pin bending and combined stress
- Verify lug net section, shear-out, and edge distance
- Resolve load sharing between clevis ears
- Evaluate fatigue, wear, lubrication, and clearance growth
- Define retention, assembly, inspection, and service strategy
