Product Overview
Product Application
DIN 965 is a standard for cross-recessed countersunk-head machine screws with a 90° flat countersunk head and metric threads. It is designed to sit flush with the workpiece after installation and is widely used in machinery, electrical equipment, sheet metal assemblies, furniture, and industrial equipment.
DIN 965 includes both Phillips (H) and Pozidriv (Z) recess types and has largely been replaced by ISO 7046, although DIN 965 remains widely available in the market.

Specification
Core Specifications & Geometry
-
Head Style: Flat / Countersunk (90° profile)
-
Drive Types: Most commonly Phillips (Type H), though Pozidriv (Type Z) and Torx/Hexalobular (under newer ISO updates) are also available.
-
Measurement Convention: Unlike pan-head or hex screws, the nominal length ($L$) of a DIN 965 screw includes the full height of the head, measured from the flat top surface to the very end of the thread tip.
DIN 965 vs. ISO 7046
While DIN 965 remains widely used in supply chains and legacy engineering drawings, it has been officially superseded by ISO 7046. For the majority of standard commercial applications, they are interchangeable, but there are subtle dimensional variations in head diameter (dk) and head height (k) tolerances across larger thread sizes.
Product Advantages
Efficient Alignment
Self-centering Phillips drive enables rapid tool alignment for manual or automated assembly.
Tension Distribution
Conical mating surface distributes clamping force evenly, improving vibration resistance.
Common Questions
How does DIN 965 differ from ISO 7046?
ISO 7046 supersedes DIN 965, with slight dimensional and tolerance differences.
How to prevent galling in stainless steel DIN 965?
Control installation speed and apply anti-seize lubricants.
Why matters "effective plate thickness" when using DIN 965 on hard plates?
If plate thickness is less than head height ($k$), the countersink punches through, failing clamping.
What are its typical applications?
Electronics enclosures, machinery panels, and flush-surface B2B assemblies.
