Black Flat Countersunk Head Nib Bolt DIN604 Made in China
**Black Flat Countersunk Head Nib Bolt (DIN 604) – Made in China**
A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws, but they are typically used with nuts to secure two or more components together. A hex cap screw is a type of cap screw with a hexagonal head, designed to be tightened using a wrench or spanner.
An ASME B18.2.1 compliant cap screw has tighter tolerances compared to a standard hex bolt, ensuring better fit and performance. This means that while a hex cap screw will always fit where a hex bolt is installed, the reverse may not always be true.
