First of allthe shapedrill tail screws with a drill tail at the lower endsimilar to a small drillprofessionally known as milling tailwhile the lower end of the threads of the self-tapping screws do not have a drill tailjust a smooth thread.
Secondly,in the use of different,self-tapping screws are usually used for non-metallic or iron plate hardness of the material is lowBecause the self-tapping screws can be fixed through their own threads,in the material to be drilled,extruded,tapped out the corresponding threads,so that they fit each other closely.And drill screws are mainly used for light steel structure,can penetrate the thin steel platein a variety of building structures and industrial structures on a wider range of applications.
Finally,the usage is also different.The tip of the self-tapping screw is sharpand the tail is not drilled.Therefore,before fixing,you need to use an electric drill or pistol drill in the object on the prefabricated holesand then the self-tapping screws screwed.While the drill tail screws can be used anytime,anywhere,because of its tail with a drill tailcan be in the steel platewood and other hard materials directly screwed,without the need to pre-fabricated holesand its tail can be synchronized with the process of screwing into the drilling.
To sum upthere are some obvious differences between drill screws and self-tapping screws in many aspects.Enterprises or consumers need to make a choice according to the specific scenarios and the actual needs
In this section,we will closely examine drilling screws and self-tapping screws,investigating their dissimilarities and similarities.Moreover,we will deliberate their applications and the elements to mull over when picking between themBesides,we will also briefly discuss some prevalent issues and solutions in connection with using these screws.

Detailed description of drill screws and self-tapping screws

1Drill tail screws

Drill screws are a kind of wood screws,because of its front end with a drill bit and namedalso known as self-drilling screws or dovetail screws.According to its different drilling taildrill screws can be divided into round head mizicrossplum,countersunk head (flat head)mizicrossplum,hexagonal washer,round head washer (big flat head)trumpet head and other typesDrill screws are mainly used on light steel structures or woodenabling users to quickly and accurately fasten wood panels or steel structures together.

2self-tapping screw

Self-tapping screws can form their own holes as they screw into materials,by deforming them
Self-tapping screws are a type of threaded screw that is commonly used to fasten steelironor other materials that are not overly hardThese screws are unique in that they do not require the use of nuts;rather,they can effortlessly complete the process of drilling and threading by leveraging their own strong force

Summarize

During the practical application process,it is overwhelmingly essential to make the correct selection of the appropriate type of drill screw or self-tapping screw for the dependability and efficiency of the fastening operation.Corporations or individual consumers can pick out various screw types based on their specific needs and operational scenarios,with the ultimate aim of attaining the optimum fastening result.
