Sudden impact load can cause uneven stress and cause the spring to malfunction prematurely. ❤Please do not change the inner diameter of the die spring. Because any changes will cause the spring to malfunction prematurely. ❤About installing springs correctly: when the spring is installed in a flat bottom hole without a guide rod, the depth of the hole is at least two rings of the spring. However, when there is a guide rod, the length of the guide rod must be longer than the length of the spring. Package List 10 x mould die spring
