LIFTING EYE BOLTS "MWLEB580" WHITWORTH THREADS
WW - Whitworth
WW
Whitworth threading is measured in inches (1"=25,4mm), and is characterised by a 55° angle for each crest and each groove of the threading. It was created in England and used as an international standard until its progressive replacement with the ISO Metric system.
100% MADE IN ITALY
MATERIAL
In accordance with standards DIN 580:2018 and DIN 582:2018, the carbon steel used for the construction of lifting eye bolts and lifting eye nuts is aluminium killed steel C15E (EN 10084/98).
A2 (AISI 304) or A4 (AISI 316) stainless steel is also used for the construction of lifting eye bolts and lifting eye nuts. Other materials can be employed for special applications.
SURFACE FINISHES
Non-machined lifting eye bolts and lifting eye nuts are usually supplied as semi-finished forged pieces (sand-blasted).
White zinc-plated lifting eye bolts and lifting eye nuts (minimum 8 microns) and hot-dip galvanised lifting eye bolts and lifting eye nuts (minimum 78 microns) are also ready for immediate delivery.
Other surface treatments are available on request (yellow zinc-plating, Dacromet, Delta Protekt, Delta Tone, Delta Seal, painting etc.).
These eye bolts with special threading are not included in standard DIN 580:2018 and cannot therefore be marketed as DIN 580:2018.
For this reason we have created a table named MWLEB580 (Mec Wolf Lifting Eye Bolts) by adopting the sizes of standard DIN 580 eye bolts’ unfinished bodies after machining with special threading.
For these products we guarantee the same mandatory requirements provided for by standard DIN 580:2018 and by the Machinery Directive 2006/42/CE; these products must therefore be considered to be perfectly compatible with standard DIN 580 and compliant with the Machinery Directive EN/2006/42.
