Description
Overview
DIN 965 defines a countersunk machine screw with a cross recess drive. The countersunk head is designed to sit flush in a prepared countersink, while the cross recess provides better driver engagement than a plain slotted drive.
This selected size is specified with diameter M5, length 20 mm, thread M5, pitch 0.8 mm.
Sold in multiples of '1000 pieces. 1 Box = '1000 pieces.
Material, Grade & Strength
The material and grade should be selected according to clamp load, corrosion exposure, vibration, temperature and compatibility with mating components.
Finish & Corrosion Protection
Zinc plating provides sacrificial corrosion protection for indoor and general industrial environments. Yellow passivation adds the familiar yellow/gold finish and additional protection.
Typical Uses
DIN 965 screws are used on covers, panels, electrical enclosures, sheet metal assemblies, machine guards and light-duty mechanical equipment where a flush finish and controlled screwdriver engagement are required.
Technical Tips
- Use the correct Phillips or Pozi driver type and size to avoid damaging the recess.
- Prepare a suitable countersink so the head seats flush.
- Do not use excessive torque on small countersunk machine screws.
- Match the material and finish to the corrosion exposure.
Frequently Asked Questions
What is the advantage over DIN 963? DIN 965 uses a cross recess drive, which generally gives better screwdriver engagement than a slotted drive.
