Ring Bolt  Manufacturers, Traders, Suppliers

Our portfolio is already vast with its more than 50,000 standard fasteners- good to know that our online catalogue and our employees‘ know-how keep the overview. But since norms cannot meet all requirements, our programme of products goes beyond DIN data sheets and factory recommendations: special productions according to drawings- from the special type of screws to the plate bending part- complete our offer. We have our own innovations in our programme of products as well. One of our specialties are magnetic plug systems.
They collect the abrasion in gearbox cases or serve as a specially constructed fuel level plunger in wind power stations. In addition we have been involved in further developments of suspension arrangements in the field of mining and tunnel construction. Besides we offer extended screws for which there was a special annex to the DIN norms for the open line construction. A cleverly devised and software-supported stock-keeping and assignment sale make sure that our products are also delivered to you as soon as possible and in a perfectly compiled manner.

With plain bearing, adjustable in the direction of force, can be fixed for screwing in;

In practice, a ring bolt is always used where heavy loads are to be lifted by a connecting element. A ring bolt is very robust, strong and resilient, which is why ring bolts are ideal for use as load handling elements or slinging points on machines and construction sites.
There are various types of ring bolts in the norelem product range. The ring-shaped eyelet has a thread underneath. If it has a male thread it is called a ring bolt, with a female thread it is called a ring nut. Steel versions are produced according to DIN 580, stainless steel versions are similar to DIN 580.
Grade 10 ring bolts are plastic coated and have a pivoting ring. This enables an alignment of the forces and prevents the ring bolt working loose or overtightening (lateral slinging up to 90° is possible / ring can rotate 360° when screw is tightened). The ring bolts can be used at temperatures ranging from -20°C to + 100°C.
Note: The optimum load rating is only achieved when the entire thread is screwed into the mating part.

Ring bolts rotatable high-strength grade 10
Material:Ring 1.6541 steel.
Screw steel.Version:Ring forged and high tensile tempered.
100% electromagnetic crack tested per EN 1677-1, 4x safety factor.
Plastic-coated.
Thread grade 10.9.Note:In contrast to DIN 580 ring bolts this ring bolt is rotatable, therefore the load direction is adjustable and unintended tightening or loosening is negated.
– 4x safety factor
– lateral loading up to 90° is possible
– ring can rotate 360° with tightened screw
The listed load values apply for a minimum screw length of 1x nominal thread diameter in steel with a minimum tensile strength of 363 N/mm², at an application temperature of -20 °C to +100 °C.Ring bolts DIN 580 / stainless steel similar to DIN 580Material:1.1141 steel or 1.4301 stainless steel.Version:Steel: drop forged.
Stainless steel: cast.Note:DIN 580 steel ring bolts:
For high demand lifting and handling functions in safety relevant areas (machine construction, lifting units, lifting tackle).
Stainless steel ring bolts similar to DIN 580:
For light lifting, and handling functions without special requirement, e.g. fence construction, chain barriers and light machining.
F2 load handling with max. 45° sling angle per ring bolt.
