Application:
Industrial equipment: Use shoulder shaped screws to fix the machine tool access door, which can be quickly opened without the need for tools. The shaft shoulder prevents over tightening and damages the threads.
Medical equipment: 316 stainless steel shovel shaped screws are used for adjusting components of the operating table, which are corrosion-resistant and easy to disinfect.
Electronic chassis: Shoulderless shovel shaped screws are used to fix the side panels, which require frequent disassembly and maintenance while also meeting the requirements of conductive grounding.
Food machinery: polished shovel shaped screws+USIT sealing washers, meeting hygiene standards and preventing dust accumulation.
