Nord-Lock防松垫圈，也叫防松垫片，它提供了一种不会受任何振动或动力负载影响的螺栓**锁紧系统。目前Nord-Lock垫片广泛地使用在能源、交通（铁路汽车）、矿山及其开采机械、钢结构、桥梁结构、生产制造、造船、军是等领域。主要有Nord-Lock不锈钢垫片和Nord-Lock碳钢垫片两大类。以下为Nord-Lock碳钢垫片规格尺寸参考表。

的详细介绍
Nord-Lock碳钢垫片是什么
防松垫片，也叫防松垫圈，制锁垫圈，锁紧垫圈，组合锁紧垫圈等。1982年，瑞典Nord-Lock AB公司开始致力于生产一种为螺栓连接设计的优良的**系统，其名字就叫Nord-Lock，中文意思为防松垫圈。这种垫圈提供了一种不会受任何振动或动力负载影响的螺栓**锁紧系统，这种螺栓**系统结构单一，只由具有特殊凸轮齿面并预先组合的一对垫圈构成。经过不断的技术更新和研发，Nord-Lock防松垫圈逐渐成为目前世界上*高效的一种螺栓**紧固系统。Nord-Lock碳钢垫片，由EN 1.7182或者等同材质制作，表面镀锌，淬火处理。
Nord-Lock碳钢垫片由两片相同的垫圈组成一套，每片的上、下面带有不同锯齿。一面为凸轮状大齿，其斜坡角度α大于螺栓螺纹角β，另一面为较密小齿。垫圈安装时，要大齿面相对，成对安装。小齿面分别与螺母和被紧固件接触。拧紧螺栓连接紧固件后，振动发生时，大齿面会错动抬升，并由α角大于β角的原理来锁住螺栓，使之不能松动。
Nord-Lock碳钢垫片不是利用摩擦力而是利用机械结构锁紧。它是由一对有相互咬合的齿面的垫圈构成。相互咬合的角度“α”大于螺纹的升角“b”，这样就有效地阻止螺丝的松动。
