Product catalog summary

Overview: The EJOT DELTA PT® Type DS screw is designed for reliable direct assembly into thermosets, which are challenging due to their hardness and brittleness. The screw features a modified thread form, known as DS (DuroSet), to accommodate these materials.

Specifications: The DS thread form includes special grooves that assist in cutting the female thread, particularly distinct at the thread tip. This design allows for a low tightening torque and a high stripping torque, enhancing assembly reliability.

Advantages:

Reduced hole depth requirement due to less chipping space compared to traditional cutting edge screws.
Cost savings through standardization, allowing one screw type for both thermosets and thermoplastics.
Safe assembly with lead-in features.
Wider production range in terms of screw diameter and length.
Larger thread engagement area for the same insertion depth.

Technical Recommendations: The document provides specific recommendations for hole geometry, including:

Hole diameter (dh) should be 0.83 - 0.90 times the nominal screw diameter (d1).
Counterbore diameter (dc) should be d1 + 0.2 mm.
Chip space (tc) should be 0.8 to 1.2 times d1.

Development Status: The product is in the development stage, and technical data may be subject to improvements.
