FAQ
Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.
Q1What are the main features of the trilobular thread-forming screw?
Features listed in the product description on this page: anti-loosening through interference fit, faster assembly.
Q2What are the head type, drive and structure of the trilobular thread-forming screw?
The specification table on this page states: thread profile is trilobular (thread-forming). Structural details are subject to the drawing.
Q3Is the trilobular thread-forming screw thread-forming or thread-cutting?
Thread-forming (self-extruding) screws form the internal thread by plastic displacement, leaving no chips and giving a cold-work-hardened flank with higher strength; thread-cutting screws remove material to form the thread, requiring lower torque but producing swarf. For plastic and thin sheet-steel joints, thread-forming types are preferred. This section explains the mechanism; mechanical properties are verified to GB/T 3098.1, and the data for this model is taken from the specification table on this page. (Applies to this model: trilobular thread-forming screw.)
Q4What should be noted when the trilobular thread-forming screw is used in plastic parts?
Plastic parts carry a high risk of creep and stress cracking: choose a thread profile with low forming torque, control the tightening torque, drill the pilot hole to the recommended size and leave clearance; at elevated temperatures, allow for the loss of clamp load as the plastic softens. This section explains the mechanism; mechanical properties are verified to GB/T 3098.1, and the data for this model is taken from the specification table on this page. (Applies to this model: trilobular thread-forming screw.)
Q5What are the core performance and design features of the trilobular thread-forming screw?
Product description on this page: this trilobular thread-forming screw uses a trilobular thread design that taps directly into light-alloy die castings to form a thread; the interference fit provides excellent anti-loosening performance and improves assembly efficiency. ...
