Spacer made of POM - internal thread

Product specification Universal fastening elements for machine construction, electronics and... more

Product specification

Universal fastening elements for machine construction, electronics and electrical engineering

Up to 20 mm length through thread, from 25 mm onwards 2 blind threads

Chemical features:

Well suited for solvents, petrol, mineral oils and fats, alcohols and hydraulic fluids

Resistant to weak acids and alkalis

Sensitive to UV radiation, the material loses its surface gloss and embrittles when exposed to direct sunlight over longer time periods

Material properties:

POM features an interesting combination of strong hardness with dimensional stability and nevertheless high impact resistance

Shatter-proof

High toughness and hardness even at low temperatures

Very good resilience

Good resistance to stress cracking

Very good sliding and wear behavior, low friction values and good abrasion resistance

High fatigue strength with changing stress conditions (spring effect)

High dimensional stability under heat

Very high dimensional stability, thus preferred material for precision, machine and apparatus construction; suitable for narrow tolerances

Good electrical properties

Approved for food

The material features low moisture absorption, thus well suited as insulating part and for storage in humid environments

Resistant to mildew and suitable for storage in earth

Weldable; bondable only after pretreatment
