三、产品用途(Application)

六角螺母与螺栓、螺钉配合使用，起连接紧固机件作用。其中经1型六用螺母应用最广，A级和B

级螺母用于表面比较光洁、对精度要求较高的机器、设备或结构上，C级螺母用于表面比较粗糙、

对精度要求不高的机器、设备或结构上。2型六角螺母的厚度M较厚，多用于常经常需要装拆的

场合。六角薄螺母的厚度M较薄，多用于被连接机件的表面空间受限制的场合。
Hexagon nuts and bolts, screws with the use of mechanical action since the 

connections are tight. Which after a six-nut type most widely used, A-class and 

B-class nut for relatively smooth surface, on to high precision machinery, equipment

 or structures, C-class nut for rough surfaces, for less precision machinery, 

equipment or structure. Type 2 hex nut thickness M thicker, more often often required

 for assembly and disassembly of the occasion. Hexagon thin nuts M thin thickness, 

used to be connected to parts of the surface space-constrained applications.

四、产品性能(Function)

六角螺母主要应用于螺钉与电子、电脑PC板上，机板及固定是锁紧螺钉之用，代替五金紧固件螺母

用，特点是重量轻、体积小、绝缘、美观、环保、不生锈、安装方便、快捷等，符合ROHS，国标标

准紧固件，常备库存，行业通用。

Screws and Hexagon nuts are mainly used in electronics, computer PC board, board

 and locking screw fixation is the use, instead of metal fasteners nuts, characterized 

by light weight, small size, insulation, aesthetics, environmental protection, no rust 

easy installation, fast, in line with ROHS, GB standard fasteners, standing stock, 

common industry.
