HDG Grade 8.8 Square Neck Carriage Bolt
A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws.  A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASME B18.2.1 hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in. Â

Application: YF series profile extrusion lines equipped with conical twin screw extruder or parallel are used for PVC plastic window profiles, Steel-plastic composite profiles, decorative profiles, etc.
Properties and advantages:
This line features stable plasticity, high output,low sheering force, long life service and
other advantages. The production line consists of control system, conical twin screw extruder, calibration unit, haul-off unit, cutter, film covering machine and stacker. The extruder is equipped with advanced AC inverter, imported temperature controller (RKC,Japan). The calibration unit's vacuum pump and haul off unit's motors are famous brand products. After simple changing of the die and screw, it also can produce the foam profiles.
