Hex Head Bolt with shank as per ISO 898-1, IS 1364, DIN 931, 934, ASTM.
Especially hot forged head form uniform grain flow with unbroken flow line make head stronger prevent failure & add strength. Fully CNC machined form over size material ensure no de-carburising or surface crack. Rolled threaded bolts are smoother surface and close tolerance; fully formed / uniform threads provide extra shear strength & resist stripping.
KANT products are heat treated in controlled atmosphere eliminating possibilities of decarburisation or surface carburisation to ensure maximum strength and toughness.
