Product description
Compiled from the existing technical description of this product on this site
YF ZCJ elastic locating pins use an elastic self-locking structure; after insertion into the hole, elastic deformation produces a permanent radial pressure, achieving precise positioning and strong vibration-resistant locking. Suitable for light alloys and precision assemblies, the miniaturized design reduces assembly space, and installation is efficient and stable — ideal for long-term maintenance-free use under demanding conditions.

FAQ
Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.
Q1What material is the “Elastic Locating Pin” made of? What strength level does it reach?
Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.
Q2To what standards is the “Elastic Locating Pin” manufactured and accepted?
Standards marked in the specification table on this page: customer drawing / company standard; spring pin structure per GB/T 879.1 (ISO 8752). Dimensional inspection reports can be supplied with the goods; batch acceptance follows the standards above and the drawing agreed by both parties.
Q3What surface treatments are available for the “Elastic Locating Pin”? How to choose?
Surface treatment marked in the specification table on this page: black oxide / zinc plated (optional). Each coating differs in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.
Q4What applications is the “Elastic Locating Pin” suitable for?
Typical applications listed in the product description on this page: aluminum and magnesium alloy assemblies; precision instruments and optical equipment; automotive electronics and connectors; industrial automation modules. Overview: YF ZCJ elastic locating pins use an elastic self-locking structure; after insertion into the hole, elastic deformation produces a permanent radial pressure, achieving precise positioning and strong vibration-resistant locking.
Q5What standards do spring pins such as the “Elastic Locating Pin” follow?
The structure and dimensions of the coiled spring pin follow GB/T 879.1 (ISO 8752); the elastic deformation after slotting grips the pin tightly in the hole. Once installed, it withstands vibration and shock loads, and both hole and pin can be reused after removal. (Applies to this model: “Elastic Locating Pin”.)
