Why choose these Allen screw bolts?

• High load capacity: Grade 12.9 bolts are suited for structural and mechanical uses where strength matters.
• Space-saving head design: Allen socket heads allow fastening where wrench access is limited.
• Standardized sizing: DIN 912 compliance ensures compatibility with common hardware and fittings.
• Versatile: From delicate electronics (small M1.6–M3) to robust machine assemblies (M5–M10).

Typical applications

• Electronics housings and PCB mounts
• 3D printers, CNC machines, robotics frames
• Automotive components and brackets
• Industrial machinery and fixtures
• Prototyping, repairs, and custom builds

Installation tips

• Use the correct size Allen key to avoid rounding the socket.
• Tighten to recommended torque for each size — avoid over-torquing to prevent thread damage.
• For corrosion-prone environments, consider finishing (zinc plating, black oxide) or using a threadlocker.
• Apply light lubrication for easier assembly and consistent torque where needed.

Ordering & compatibility

• Select the required size (M1.6 → M10) and quantity.
• DIN 912 compatibility ensures direct replacement for other DIN/ISO hex socket cap head screws.
