Baks mushroom-head screw SGN M8×20 (pack of 100) — model 650342

Baks SGN mushroom-head screw M8×20 (pack of 100) is a set of metric fasteners designed for general mechanical assemblies, furniture fixings and metal-to-metal connections where a rounded, low-profile head is required. Each screw features an M8 thread and a 20 mm length, with a domed (mushroom) head that provides a smooth finished surface and distributes load across a wider area than a countersunk screw. The pack of 100 is intended for repetitive tasks in repair, construction and production environments, offering a consistent supply of identical fasteners.

Advantages

The mushroom head offers a visually neat, low-profile finish and reduces the risk of snagging or catching. Standard M8 metric threading ensures compatibility with common nuts and pre-tapped holes, while the 20 mm shank length is suitable for a range of thin-to-medium thickness connections. Supplied in a pack of 100 pieces, the set simplifies stock management for workshops and reduces the need for frequent reordering.

Suitable for

• Furniture assembly and fittings where a rounded head is preferred
• Metal-to-metal connections in machinery and enclosures
• Repair and maintenance tasks requiring multiple identical fasteners
• Light construction and mounting of brackets or panels

Key specifications

• Thread: M8 metric
• Overall length: 20 mm
• Head style: mushroom (domed) head
• Quantity: 100 pieces per pack
• Intended use: general mechanical and furniture fixings

How to use

Select compatible female threads or nuts rated for M8 fasteners and ensure the mating thickness matches the 20 mm screw length. Pre-drill or use pre-tapped holes where appropriate; insert the screw and tighten with the correct driver or wrench for the screw head type and drive. Apply recommended torque for M8 fasteners in the specific material to avoid over-tightening and to ensure a secure connection. For repeated assembly tasks, organize screws by size and head type to speed up installation.

Usage recommendations

For best results, pair these M8×20 mushroom-head screws with compatible M8 nuts or tapped holes in materials of appropriate thickness. Inspect the mating surfaces for debris or damage and use washers if increased bearing area or corrosion protection is required. Store the pack in a dry environment to prevent surface corrosion prior to use.
