M4 x 20mm Hex Set Screw | DIN 933 | A4 Stainless Steel
This M4 x 20mm Hex Set Screw combines a fully threaded body with a hex head drive, giving installers a secure fixing for metalwork frames.
The A4 stainless steel construction suits exposed fittings, marine hardware and installations where long-term corrosion resistance is required. The fully threaded layout helps maintain grip along the complete shank, which is helpful for slotted brackets, adjustment points and serviceable assemblies.
Common Applications
- Laboratory frames, equipment stands and specialist instrument brackets
- General engineering where a hex head screw is easier to access than an internal drive
- Machinery guarding, motor mounts and equipment service panels
- Electrical enclosures, control cabinets and instrument housings
Why Choose This Fully Threaded Hex Screw?
- Fully threaded 20mm body helps support consistent engagement through the joint
- 7mm across flats head allows fitting with common spanners and socket tools
- The shorter body suits brackets, covers and service panels where a neat fixing is required without excess thread beyond the joint.
