普遍V 型螺纹丝锥全部载荷的70%都集中在第一扣刀齿上,这往往会因承担大量的过应力和疲劳使大多数刀齿折断.用Spiralock 丝锥加工出的螺纹具有独特的30°楔形斜面,不但能分担压缩载荷,且无需使用其它紧固件.只要不施加紧固载荷,斜面也就不会影响内外螺纹相互间的自由旋转.这样,螺纹齿顶就会与楔斜面紧紧啮合在一起,从而使全部刀齿形成连续的螺旋形接触,将紧固力更均匀地分布在 Mostly 70% of the full load of a common V-Tap is centered on the first buckle, which often breaks most of the teeth due to a significant amount of stress and fatigue.The threads machined with the Spiralock tap have a unique 30 ° Wedge bevel, not only to share the compressive load, and without the use of other fasteners. As long as no tightening load, the bevel will not affect the free rotation of the internal and external threads with each other. Mesh together so that all the teeth form a continuous helical contact, distributing the fastening force more evenly
