Fasteners for machinery and furniture that promise durable, corrosion-resistant fastening, suitable for indoor and humid outdoor use: Drenky Cylinder Screws. Consistent threads and a hexagon socket give installers confidence during high-torque tightening. Are these M6 x 20mm screws the right choice for recessed or heavy-duty applications?
⚡ At a Glance
- • Thread Quality: Fully threaded M6 x 20mm with smooth, burr-free threads for consistent grip
- • Best for: Installers, maintenance crews and DIYers needing reliable M6 fixings
- • Not ideal for: Applications requiring specialised coatings for highly corrosive environments
M6 x 20mm fully threaded cylinder head screws made from 304 stainless steel, manufactured to DIN 912 (ISO 4762). Hexagon socket drive enables higher torque and reliable fastening.
Long-lasting corrosion resistance - thanks to 304 stainless steel
Grade 304 stainless steel resists surface oxidation in humid environments while retaining toughness and tensile integrity. The alloy composition reduces the rate of rust compared with plain steel fasteners.
Suitable for indoor and humid outdoor use, cutting the need for frequent replacements. Durable finish keeps joints secure over time.
Secure torque transfer - with hexagon socket (Allen) drive
Internal hexagon drive increases contact area between driver and head, lowering the chance of cam-out under load. The socket design allows higher torque to be applied safely compared with slotted or Phillips heads.
Easier tightening in high-torque situations such as machinery mounts and bracketry. Reduced slippage means fewer rounded heads and faster installations.
Flush-fitting applications made simple - with cylindrical head and full thread
Cylindrical socket cap head is sized for recessed or countersunk accommodation while the fully threaded shank provides engagement along the length of the fastener. Compliance with DIN 912 (ISO 4762) ensures consistent dimensions.
Ideal where a neat, recessed finish is needed and where axial grip matters, for example TV mounts and furniture fixings. Pack of 20 supports batch installations and maintenance spares.
