Hex head
Hex head screws and hex-head bolt types are widely used in industry, machinery and structural connections thanks to high torque transfer, a broad contact surface and easy socket-tool assembly.

Allen head
Allen head screws offer controlled tightening in narrow assembly areas with their internal hex drive structure. They are a compact head type preferred in machine components, mold systems and precise technical connections.
Countersunk head
Countersunk screw types create a flush finish by seating into the surface. They are used in sheet metal screws, wood screws and decorative assembly applications for a clean appearance and minimal surface protrusion.
Pan head
The pan head form provides a low profile and a broader bearing area, supporting balanced load distribution on thin sheet, panel and sensitive-surface parts. It is a practical head type for general assembly and machinery connections.
Mushroom head
Mushroom head screws provide a smoother finish on visible surfaces with their domed upper form and softer geometry transitions. They are often preferred in furniture, trim, accessory and decorative connection applications.
Flange head
Flange head screw and flange bolt types improve load distribution by creating a broad seating surface under the head. This geometry can reduce washer use and suits serial assembly, sheet connections and vibration-prone environments.
Washer head
Washer head screw types reduce crushing on thin materials and distribute clamping force more evenly thanks to the wider bearing area under the head. They offer advantages in sheet assembly, panel joining and serial production applications.
Torx head
Torx head screws provide more controlled torque transfer with a higher contact surface and reduce cam-out risk. They are a modern head type frequently used in automotive, white goods, technical service and serial assembly lines.
Phillips head
Phillips head screws are widely preferred in general fasteners, sheet applications and panel assembly because of broad driver compatibility and quick installation advantages. They are among the classic screw head forms with practical use.
Hex socket head
Hex socket head screws provide a clean outer surface, compact assembly and high tightening control thanks to their internal hex geometry. They are widely used in technical equipment, machine parts and precise mechanical connections.

FAQ
Can you produce different lengths?
Yes. Length and diameter combinations are reviewed as project-based manufacturable ranges.
How should I choose A2 vs A4?
A2 (304) fits many general environments, while A4 (316) is preferred for more aggressive exposure conditions.
Which standards should I reference?
Reference standards depend on geometry and application, and are finalized during technical review.
How do I read dimensions?
Use the parameter table together with the glossary definitions.
Can I request technical support?
