Metric DIN 6334, DIN 1479 and DIN 88087 Coupling Nuts

Steel Zinc, Plain, Left and Right Hand Threading


Metric Coupling Nuts or Rod Couplings are extra high (long) hex nuts designed to attach two threaded rods or bolts. Din 6334 were formally known as Din 934 XH, basically an extra high hex nut with length being 3X thread diameter. Din 8807 are are slightly longer at 3.5-4X thread diameter. Din 1479 are coupling nuts where one side is right hand thread and the other side is left hand thread, functioning like a turnbuckle, tightening both rods by turning nut.
