CLASS 4 GALVANISEDSTEEL DIN 439
Low-profile hexagon nut DIN 439 Class 4 — galvanised
Lock nut | Metric thread | Strength class 4 | Zinc coating Zn
Product description
The low-profile hex nut to DIN 439 is a fastener with a reduced height, designed for metric threaded connections. Due to its design, it is often used as a lock nut, a support nut or in situations where limited installation space prevents the use of a standard hexagon nut.
The product is made of steel in strength class 4 and has a zinc coating. The zinc coating reduces the risk of corrosion under typical operating conditions, whilst the hexagonal shape allows for quick assembly using standard flat-bladed, ring or socket spanners.
The DIN 439 low-profile nut is compatible with bolts, threaded rods and other components with metric threads of the appropriate size. It is a practical solution for assemblies requiring securing, adjustment or a limited overall height of the assembly.
Features and benefits
- Low-profile design — useful where installation space is limited
- Locking function — can be used as an additional lock nut to secure the joint
- Strength class 4 — for standard assembly and technical applications
- Zinc coating — reduces the risk of corrosion under typical operating conditions
- Metric thread — compatible with screws and threaded rods of the corresponding size
- Hexagonal profile — easy to use with standard assembly tools
Applications
- Locking bolted joints and securing nuts
- Assembly of machinery, equipment and auxiliary structures
- Connections with threaded rods in technical installations
- Construction, metalwork, maintenance and workshop work
- Applications requiring a low joint height
