Areas of application screw link Stainless steel

The product is very popular in many areas, such as:

• to lower off-climbing anchors for rappelling
• in glue in bolt for retreating / rappelling
• in expansion bolt for retreating / rappelling
• as an abseiling point in cave exploration
• for the fixed connection of gear for work at heights
• in the field of mountain rescue and cave rescue
• Fixed connection of ascender with webbing slings / stepladders

Watch out for galvanic corrosion!

If you install a screw link stainless steel fix, you must pay attention to galvanic corrosion! This means that you must not hang this stainless steel product in a zinc plated steel fixed point. This will lead to corrosion of the fixed point over time.

Please always combine zinc-plated components with other zinc-plated components such as bolt hanger combine. If the fixed point is made of zinc plated steel, you must use a link with the same steel quality. This is the only way to ensure long-term durability. I.e. for many years.

Problematic DIY store screw links

Unfortunately, non-standardized products from the DIY market keep turning up at abseiling points. Watch out! These can be life-threatening. The breaking loads are often only a few hundred kilos. Consequently, these links do not meet any standards.

Only use standardized products such as the screw link stainless steel. They are clearly recognizable by the markings on the side. Only standardized material should be used in the above-mentioned areas.

screw link Note types!

There are many different models of quick links. The oval shape of the screw link stainless steel is the classic one. It is mainly used for vertical force transmission of narrow ropes or steel components. This is because the inner radius is only 10 mm. For example, from a glue in bolt to an 8mm rope. Or from the metal ring of a work at heights harness to a webbing sling or energy absorber.

Depending on the intended use, these shapes may also be more suitable:

• D-shaped: for attaching several securing points as with the work at heights
• Triangular: to transfer loads from a small attachment point to a slackline, for example
• rectangular: for lifting work such as connecting sling to sling
• pear-shaped: on the one hand where large screw openings are required or wide components are to be suspended on the other hand
• oval: classic design for all vertical force transmissions

Practice tip

Anyone who uses screw link stainless steel regularly should maintain it. Yes, exactly! W A R T E N! This can be the case with work at heights, for example. Here you have to hang the link in and out of the harness or rigging plate again and again. This means you are well advised to lubricate it with a climbing equipment care oil. This means that the screw lock can still be operated easily!
