Flanged Sleeve Bushing — ISO / DIN (Series 135) are used primarily for a range of mechanical fastening duties. This page summarizes where they fit, the industries that rely on them, and the practical points to get right when you specify them — to ISO / DIN. Stocked across roughly M6 to M50, they cover general to heavy-duty work.
Typical Applications for Flanged Sleeve Bushing — ISO / DIN (Series 135)
The most common settings where these are specified:
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
How to Specify Flanged Sleeve Bushing — ISO / DIN (Series 135) for Your Application
- Size: Match the nominal size to the mating thread or hole. This product spans M6–M50; check the full table below for the exact dimensions of each size.
- Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to ISO / DIN. Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Flanged Sleeve Bushing — ISO / DIN (Series 135) Are Not the Right Choice
Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.
