As the requirements for fixing objects continue to improve and evolve, the demands on self-drilling screws have also increased. Therefore, self-drilling screws have undergone corresponding improvements, including the emergence of high-strength self-drilling screws. Today, we’ll examine the optimizations in strength aspects of self-drilling screws.
High-strength self-drilling screws offer advantages such as low locking torque, high locking force, high holding force, excellent anti-loosening effect, no cutting dust, and low heating during locking, allowing for quick operation. They also eliminate the need for pre-tapping the pilot hole, have strong anti-loosening force eliminating the need for anti-loosening washers, and offer superior strength, making them more convenient to use. The formed part of the self-drilling screw is a cone composed of several cutting edges. During assembly, drilling, tapping, and tightening can be completed in one step, saving time and effort.

DIN 931-style half-thread and DIN 933-style full-thread hex bolts should not be selected from diameter and overall length alone. The practical choice depends on the joint stack, required grip, location of the thread transition, available nut engagement, mating hardware, material or property requirement, coating system and governing product specification. A half-thread bolt is not automatically […]
A bolt manufacturer should be evaluated against a defined joint, drawing and acceptance plan—not a product list or unit price alone. Buyers need to verify whether the supplier can manufacture the required geometry, control material and heat-treatment requirements where applicable, manage threads and coatings as one dimensional system, inspect critical characteristics, preserve batch traceability and […]
