5N.m500N金属接骨螺钉自攻力扭矩试验系统，测量具有自攻性能的金属接骨螺钉旋入标准材料时所需轴向自攻压力荷载值。测量旋入扭矩荷载和轴向位移变量值。测量接骨螺钉轴向拔出力、旋入旋出旋动扭矩、轴向插入力。
→自攻螺钉测试范围：HA/HB/HC/HD1.5-8.0mm；标称直径1.5-3.5-8.0mm。
→轴向压力荷载传感器0～500N，精度0.5%FS，分辨力0.01N；
→旋转扭矩荷载传感器0～5N.m，精度0.5%FS，分辨力0.001N.m；
→试验速度：旋转扭矩力以30r/min恒定速率施加，轴向压缩荷载以2N/s恒定速率递增。
→自攻力最大预载荷1.0N，以保证螺钉和工装紧密契合。
→旋入旋出旋动扭矩按照3r/min速度施加扭矩于螺钉头部，旋转4圈的扭矩值为最大旋入扭矩。反向旋转4圈螺钉测量旋出最大扭矩。旋入和旋出试验过程中施加不大于11.7N轴向载荷。
→HRJ-Test自攻力扭矩试验测控软件（多通道多功能易操控），采集频率1000Hz，实时记录处理分析轴向压力、扭矩、轴向位移。同时记录两个Y轴数据（Y轴1为力和扭矩，Y轴2为位移）随时间的变化。
→试验数据获得及判断：一次有效的试验从自攻开始后完整旋转5圈，将自攻开始后获得的最大轴向力作为自攻力记录。有时在初始的5圈旋转过程中，接骨螺钉将出现自攻后停止进入试验块（停止或试验块内螺纹破坏），计算机软件显示扭矩阻力的急速降低和轴向位移的保持不变（平线）。当接骨螺钉停止时，轴向力重新以2.0N/s±1.0N/s速率增加重新获得自攻：（1）第2次出现的最大轴向力作为自攻力记录；（2）在第2次自攻开始后试验样品需完成5圈旋转；（3）报告中备注试验样品停止或试验块内螺纹破坏。超过一次以上停止的试验样品视为无效。
