螺栓，螺釘成品楔負(fù)載拉力試驗(yàn)機(jī)
1.簡介
該螺栓，螺釘成品楔負(fù)載拉力試驗(yàn)機(jī)可以測定螺栓和螺釘成本的抗拉強(qiáng)度和頭與無螺紋桿部或螺紋部分交接處的牢固性。
螺栓和螺釘成品楔負(fù)載試驗(yàn)用楔墊，該試驗(yàn)裝置具有足夠的剛性，可以確保彎曲發(fā)生在頭與無螺紋桿部中螺紋部分的交接處。
Wedge loading of finished bolts and screws, this testing device is rigid to ensure that bending occurs on the transition section between the head and the unthreaded shank or the thread.
