Bolt with full thread Koelner DIN 933 8x16 mm A2 stainless steel, pack of 4

Koelner bolt with full thread DIN 933, size 8x16 mm, made of A2 stainless steel and supplied as a pack of 4. This hexagonal-head, fully threaded M8 bolt is designed for general fastening tasks where moderate corrosion resistance is required. The A2 stainless steel offers standard rust resistance suitable for indoor and mildly humid environments, and the DIN 933 specification ensures consistent thread form and fit for nut-and-bolt assemblies.

Advantages

The bolt combines a full thread profile with a hex head to allow secure clamping along the entire shank and easy torque application with conventional wrenches or sockets. A2 stainless steel construction provides durability and resistance to oxidation in non-aggressive environments. Conformance to DIN 933 ensures dimensional accuracy and thread compatibility with standard M8 nuts and threaded components.

Suitable for

• Metal and wood assemblies requiring M8 fastening
• Machinery repairs and maintenance where standardized bolts are needed
• Construction fixtures and fittings in indoor or sheltered locations
• Furniture assembly and joinery with moderate exposure to humidity

Key specifications

• Thread type: full thread (through-thread) compatible with M8 nuts
• Thread standard: DIN 933 thread form
• Size: nominal diameter 8 mm, length 16 mm
• Head type: hexagonal head suitable for wrench or socket drive
• Material: A2 stainless steel (austenitic grade) for general corrosion resistance
• Quantity: pack of 4 pieces

How to use

Select the appropriate M8 nut or tapped hole that matches the bolt's thread pitch and start threading by hand to align threads. Use a suitably sized spanner or socket to tighten the hex head to the required torque for the application, taking care not to exceed recommended torque values for M8 fasteners in A2 stainless steel to avoid thread damage. For through-bolted joints, ensure mating surfaces are properly prepared and use washers where needed to distribute load and protect surfaces.

Usage recommendations

For applications exposed to marine or highly corrosive atmospheres, consider a higher corrosion resistance grade such as A4 stainless steel. When fastening into soft materials or thin sheets, use appropriate washers and avoid over-tightening to prevent pull-through or deformation. Store bolts in a dry environment to maintain condition prior to installation.
