Drill Tail Screws

Shuifu Hanyang Machinery Technology Co., Ltd. will take you to understand the following series of problems that may occur during the use of drill tail screws,
Some are quality issues with the product itself, while others are operational issues. The specific analysis is as follows:
1. The tail screw cannot be fully inserted into the cross groove during operation due to two reasons: a. Defects in the cross groove caused by the breakage of the punching pin; b, Quality issues with the batch head itself, or severe wear and tear on the batch head, rendering it unusable.

2. During use, the drill tail screw may experience tooth jamming or tooth burning red phenomenon (i.e. the drill tail part has already penetrated the iron plate tooth and cannot enter smoothly) or fracture, due to the following three reasons: a. The outer diameter of the tooth is too large, which is a quality problem of the drill tail screw; b, Incorrect operation method, resulting in drilling deviation during operation; c, The specifications of the selected drill tail screw are incorrect, causing it to break and jam beyond the normal range of use.
3. When the drill tail screw slips out during operation, it means that the drill tail and teeth have already penetrated the iron plate and cannot be locked tightly. There are two reasons for this: a. The outer diameter of the teeth is too small; b, The iron plate is too thin, the tooth spacing is large, and there are problems with the locking fit.
4. There are several reasons for the occurrence of broken ends, inability to penetrate, and burnt ends of the drill tail screw during use, including: a. The hardness of the product core is too high, resulting in broken ends; b, The R angle under the product head is not large enough, resulting in a broken end; c, The hardness of the attacked material itself exceeds that of the drill tail screw, resulting in broken ends and inability to penetrate; d, Drill the tail screw. If the tail width is small, it may cause a broken end, making it difficult to penetrate and burning the tail; e, The selection of specifications is unreasonable or exceeds the normal range of use, resulting in broken heads, inability to penetrate, and burnt tails.
Small screws are big articles. Only by doing every detail well and strictly controlling the process can we make qualified and high-quality screws. Jingrunlong strictly implements standardized quality management processes, including incoming material inspection, process inspection, finished product inspection, and factory inspection. The quality control procedures cover the entire process from raw material procurement, production and processing, packaging and transportation to after-sales service. Jingrunlong strictly implements self inspection, mutual inspection, and special inspection systems to eliminate unstable factors that affect quality from all aspects and throughout the entire process. Jingrun Long only produces high-quality fasteners. Jingrunlong brand's high-strength self drilling and self tapping precision screws include various types of countersunk self tapping screws, pan head self tapping screws, countersunk head drill tail screws, pan head drill tail screws, hexagonal flange drill tail screws, Huasi head drill tail screws, hexagonal wood screws, countersunk fiberboard screws, guide screws, etc. The products are widely used in colored steel plates, light steel structure engineering, steel aluminum doors and windows, advertising industry, refrigeration and air conditioning, home appliance manufacturing industry, enamel steel plates, wooden furniture, aluminum curtain walls, decoration and decoration, etc., and are exported to Europe, America, Japan and other countries.
