Characteristics

• A keyed female-thread reinforcing insert.
• The key mechanically locks the rotation so there is no risk of it falling out.
• With the high strength of integrated stainless steel, it is usable for firm fastening or in areas where bolts are frequently fastened and removed.
• It is ideal for reinforcing female threading in light metals, castings, resin etc., as well as for repairing damaged female threading.
• No special technique is required for insertion.
• Mounting is even easier than with coil-type inserts. Use the dedicated tool SKK（SKK）.

• Coil-type inserts and special surface treatment specifications are also available. Please contact our customer service.
