## Summary description

Koelner DIN 933 hex head cap screw, M8×30 mm size with full metric thread and A2 stainless steel material. Supplied as a pack of 4, this fastener is suitable for general mechanical assemblies, metal and wood connections, and corrosion-resistant indoor or outdoor fixing where medium strength stainless steel is required.

## Long description

Koelner DIN 933 hex head cap screw M8×30 mm is a full-thread stainless steel fastener designed for general mechanical and construction use. Made from A2 stainless steel and conforming to DIN 933 form, this M8×30 screw offers corrosion resistance and a consistent metric thread profile suitable for many indoor and outdoor applications. Supplied as a pack of 4, the screw is intended for assemblies where moderate corrosion resistance and reliable clamping are required.
Advantages
The full-thread design provides continuous engagement along the shank, improving grip in through-bolt and into-threaded-plate connections. A2 stainless steel offers a balance of strength and corrosion resistance for nonmarine environments, while the hex head allows for easy installation and removal with standard spanners or sockets. The DIN 933 form ensures dimensional consistency and compatibility with common metric nuts and tapped holes.
Suitable for
General mechanical assemblies and repair work
Joining metal parts, brackets, and frames
Fixing wood to metal where a durable screw is needed
Indoor and outdoor fixtures where moderate corrosion resistance is sufficient
Key specifications
Thread type: full metric thread
Thread size: M8
Length: 30 mm
Head type: hex head cap screw
Material: A2 stainless steel (austenitic stainless)
Corrosion resistance: suitable for general atmospheric conditions
Package quantity: 4 screws
How to use
Select matching M8 nuts or a tapped hole of appropriate class and ensure mating surfaces are clean and aligned. Insert the screw through the components to be joined and engage the nut or thread, tightening with an appropriate spanner or socket until secure. For repeatable clamping, use a torque wrench and follow recommended torque values for M8 fasteners in A2 stainless steel, taking into account material thickness and joint design.
Usage recommendations
For best results, avoid use in highly chlorinated or marine environments where A2 stainless steel may corrode over time; consider higher-grade stainless if necessary. When fastening soft materials, use washers to distribute load and reduce pull-through. Store in a dry place to preserve corrosion-resistant properties.
