## Long description

Koelner hexagon head bolt DIN 933 is a fully threaded fastener in size 5x16 mm made from A2 stainless steel and supplied as a pack of six. The standard metric thread and hex head allow installation with common spanners and sockets. Designed to provide corrosion resistance and reliable clamping in a wide range of general mechanical and assembly applications, this bolt follows DIN 933 specifications for head shape and thread runout.
Advantages
This stainless steel bolt offers corrosion resistance appropriate for indoor and many outdoor environments where A2 stainless steel performance is suitable. Full threading along the shank provides continuous engagement with nuts or tapped holes, allowing flexible placement and fine adjustment of clamp length. The hex head design ensures easy torque application with standard hand tools and sockets, facilitating quick assembly and disassembly during maintenance or repairs.
Suitable for
Household repairs and DIY projects
Furniture assembly and fittings
Light machinery and equipment assembly
Metal and wood joining where a standard metric bolt is required
Applications requiring moderate corrosion resistance
Key specifications
Bolt type: Hexagon head, fully threaded (full shank thread)
Thread size: M5
Length: 16 mm (total length of the bolt)
Material: A2 stainless steel (austenitic stainless steel grade providing corrosion resistance)
Standards: Conforms to DIN 933 geometry for head and thread profile
Pack quantity: 6 fasteners
How to use
Select a matching M5 nut or threaded hole with appropriate thread engagement and ensure mating parts are correctly aligned. Insert the bolt through the assembled components so the hex head sits flush against the surface, then tighten using a suitable spanner or socket until the required clamping force is reached. For repeated assemblies, inspect threads for damage and clean before reinstalling. When using in environments with higher corrosion risk, consider compatible washers or coatings to extend service life.
Usage recommendations
Use appropriate hand tools to avoid rounding the hex head and apply recommended torque for M5 stainless steel fasteners. Avoid excessive overtightening which can cause thread deformation; when fastening into softer materials, use washers to distribute load and prevent pull-through. For critical or high-corrosion environments, consider higher-grade stainless steel or additional protective measures.
