Standard: ASME, DIN, GB, BS, etc. Special sizes can be customized
Basic packaging: plastic bag + neutral carton (without logo) + solid wood palle

Hex Head Bolt are hexagon head bolts (partial thread) and hexagon head bolts (full thread).
Hex Head Bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), which must be used with a nut to fasten two parts with through holes.
This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Features

• Precision dimensions (±0.05mm tolerance on critical surfaces) ensure proper fit with M8 fasteners, eliminating looseness in assemblies

• Electrical conductivity (15% IACS) enables effective grounding in electrical enclosures, reducing electrostatic discharge risks

• Corrosion resistance in damp and industrial environments, outperforming carbon steel washers by 500% in humidity testing

• Controlled ductility allows conforming to surface irregularities while maintaining structural integrity, preventing leaks in fluid systems

• Non-magnetic properties eliminate electromagnetic interference in sensitive equipment like medical devices and sensors

Applications

Essential for electrical junction boxes, automotive electronic control units (ECUs), marine hardware fittings, and precision machining centers. Used in conjunction with hex bolts, studs, and socket screws to protect painted or machined surfaces, distribute clamping force, and ensure electrical continuity in grounded systems .
