Hexagon Head Bolts Partial Thread A2 stainless steel - DIN 931 Variant in A4 stainless steel

Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

Reinforced threaded inserts allow threaded holes which have been damaged, torn out or jammed to be used again or to be repaired. This makes it possible to recover scrap and rejects of expensive products. Reinforced threaded inserts are suitable for use in various materials, including light metals and casting. Inserts with internal threads larger than M6 are supplied with four locking pins instead of two. Permissible deviations: The medium tolerance class applies to the threads listed, i.e. 6H for nut threads and 6g for bolt threads. Other dimensions ±0.25 mm. With reinforced threaded inserts we also offer a version with a stronger cross-section for use in applications with greater stress. Technical information see operating instructions for threaded inserts.

The required torque is set by a set screw and a graduated scale. The set value can be secured using the lateral clamping screw. When the set torque is reached the grip audibly and palpably releases. The loosening torque is higher than the tightening torque so that the torque handle can be released without any problems. The internal thread version has a hole in the set screw so that the torque handle can also be used on threaded rods. Set torque accuracy ± 5%. On request: Other thread lengths.
