screw link 12mm zinc plated

The screw link 12mm zinc plated is a real workhorse. And for good reason. Firstly, the breaking load is extremely high at 60 kN. Secondly, the price is absolutely top class. And thirdly, the product complies with EN standard 12275 and EN standard 362, which means it can be used in many areas where compliance with standards is important. For example in the work at heights area.

Areas of application screw link 12mm zinc plated

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
• in the field of mountain rescue and cave rescue
• For very high loads such as material transportation
• for rope bridges such as the Flying Fox or Tibetan Bridge

Watch out for galvanic corrosion!

If you install a screw link 12mm zinc plated, you must pay attention to galvanic corrosion! This means that you must not hang this zinc-plated steel product in a stainless steel fixed point. This will lead to corrosion of the quick link over time.

Please always combine zinc-plated components with other zinc-plated components such as bolt hanger. If the fixed point is made of stainless 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 12mm zinc plated. 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 12mm zinc plated is the classic one. It is mainly used for vertical force transmission of narrow ropes or steel cables or steel components. This is because the inner radius is only 14mm. For example, from a glue in bolt to a 12mm steel cable.

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 a screw link 12mm zinc plated 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 keep hanging the link in and out of the harness or rigging plate. 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!
