About this product
This parallel pin is manufactured from steel and measures 4mm in nominal diameter by 20mm in length, conforming to the DIN 7 standard. It serves as a rigid mechanical fastener designed to maintain precise alignment between connected components or act as a shear pin in machinery. Buyers select this specific type for its ability to provide stable positioning without interfering with assembly tolerance requirements. To choose the correct size, ensure the hole diameter matches the 4mm specification while verifying that the 20mm length accommodates the total thickness of the joined parts, including any headspace or protrusion needed for your application.
APPLICATIONS
- Used by machine engineers to align gearboxes and couplings during assembly.
- Installed by maintenance teams to secure pivots in automated conveyor systems.
- Applied by manufacturers to fix relative positions of structural brackets.
