Hex Head Screw Baks 991020 A2 SSZ 10×20 mm stainless steel

Hex head screw Baks 991020 A2 SSZ 10×20 mm stainless steel is a stainless fastener with a hexagonal head designed for installation with a wrench or socket. With nominal dimensions 10×20 mm and corrosion-resistant A2 stainless steel construction, this fastener is intended for mechanical joining in applications where exposure to moisture or mild corrosive conditions is expected. The screw offers a conventional hex drive and a length suitable for joining thin metal plates, wooden components, and light-duty assemblies.

Advantages

The stainless A2 material provides good resistance to rust and oxidation in outdoor and humid environments. The hex head design allows secure torque application with standard wrenches or sockets, reducing the risk of slippage during installation. Its standardized dimensions ensure compatibility with common drilled holes and mating nuts, enabling straightforward replacement and maintenance. The screw's durable finish retains mechanical integrity under typical service conditions found in building, machinery, and equipment assembly.

Suitable for

• Joining metal sheets and light structural elements
• Wood-to-metal assemblies
• Mounting components in machinery and equipment
• Outdoor fixtures and installations exposed to moisture
• General maintenance and repair tasks requiring corrosion-resistant fasteners

Key specifications

• Head type: hexagonal head for wrench or socket drive
• Material: A2 stainless steel (corrosion-resistant grade)
• Nominal diameter and length: 10 × 20 mm
• Typical applications: mechanical fastening in metal and wood constructions
• Finish: stainless (natural passivated surface)

How to use

Select a compatible nut or tapped hole and ensure mating threads match the screw's diameter and pitch. Pre-drill holes to the recommended clearance or pilot size for the materials being joined. Use an appropriately sized wrench or socket to apply torque evenly to the hex head; avoid excessive torque that could strip threads or deform the fastener. For assemblies exposed to vibration, consider using a locking washer or thread-locking compound compatible with stainless steel.

Usage recommendations

For optimal corrosion resistance, avoid contact with dissimilar metals without insulating materials, and tighten to recommended torque values for the specified diameter to prevent galling. Store screws in a dry environment and clean mating surfaces before installation to maintain long-term performance.
