**China Manufacturer - Non-Standard Grade 8 Black Coated T-Head Bolt**
A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws, but they are typically used in conjunction with nuts to create a secure connection. A hex cap screw is a type of cap screw with a hexagonal head, designed to be driven by a wrench or spanner.
An ASME B18.2.1 compliant cap screw has tighter tolerances than a standard hex bolt for the head height and shank length. This means that an ASME B18.2.1 hex cap screw will always fit where a hex bolt is installed, but a hex bolt might be slightly too large for a design that requires a cap screw.

The Swiss slitting machine tool, also known as the Swiss lathe or core lathe, differs from a conventional knife lathe in that it features longitudinal cutting via spindle extension movement rather than tool rest extension movement. Its primary advantage lies in its ability to turn slender shaft parts with diameters below 3mm and length-to-diameter ratios greater than one.
