Dowel Pin Shear Screen
Calculate nominal dowel-pin shear stress from applied load, pin diameter, number of pins, and shear planes.
Preliminary design support. Your inputs and results stay in this browser.
WHAT THIS SCREEN ANSWERS
Dowel pins locate parts and can transmit shear when the load path is intentional. Total nominal shear area follows from pin diameter, count, and stated shear planes. Start from the operating condition that makes this question consequential.
Clearance, fit, hole quality, bending, bearing, and uneven load sharing can change which pin governs. Confirm pin fit, material, hole tolerance, bearing, fatigue, and assembly method. It is a reason to continue the decision chain.
Dowel pins locate parts and can transmit shear when the load path is intentional. Clearance, fit, hole quality, bending, bearing, and uneven load sharing can change which pin governs. Use the output to direct data collection instead of hiding the data gap.
Total nominal shear area follows from pin diameter, count, and stated shear planes. Confirm pin fit, material, hole tolerance, bearing, fatigue, and assembly method. The decision remains specific to this application because dowel pins locate parts and can transmit shear when the load path is intentional. Escalate when the consequence exceeds a preliminary screen.
