普通型自攻快速锁紧螺母
这些快锁快扣螺母可以在塑料外轴、压铸件或低碳钢螺柱上形成自己的螺纹。螺纹成形在不产生切屑的情况下完成。而且尤其需要说明的是信诺华工业自攻快速锁紧螺母是可拆卸和可重复使用的。
六角快扣螺母的高度很低，外部尺寸小，因此在空间受限的地方非常理想。通常采用带内六角套筒的工具完成安装。
弹性锁紧作用提供了抗振动和牢固的装配效能。
信诺华工业自攻快速锁紧螺母典型应用包括工业机械制造、电子控制零组件、医疗设备、机动车辆、家用电器和音响设备等。

带垫型自攻快速锁紧螺母
和普通款式一样，这些垫圈型自扣紧快锁螺母一样实现快速安装，实现对光轴和螺杆的扣紧定位
但加大外径的垫圈增加了受力面积，同时带垫结构的弹性缓冲了拧紧时的冲击，使底部被安装件不会断裂或损坏（尤其是当快锁安装螺母应用在易碎部件上时）。
这将最大限度地减少金属板的变形或组装过程中易变形塑料或陶瓷零件的变形或损伤。

Self-Threading push on Nut - Hex
MPN:138852003 Tinnerman SR375011-598

Self-Thread Hex Nut Stud Size 3/8-11/16 Drive Zinc Mechanical

SELF-THREADING NUTS - REGULAR TYPE
These Self-Threading Nuts form their own thread on plastic, die cast or mild steel studs. The thread-forming displaces material without producing swarf. They are removable and reusable. Self Threading Nuts have a low height and small exterior dimensions so they are ideal where space is restricted. Where there is insufficient clearance for standard tools, a special internal hex wrench can be used.

Typical applications include electronic equipment,conveyors, plastic bosses, toys, motor vehicles, domestic appliances and audio equipment.

Material - Austempered Carbon Steel

SELF-THREADING NUTS - WASHER TYPE
These Washer-type Self-Threading Nuts form their own thread on plastic, die-cast or mild steel studs. The thread-forming displaces material without producing swarf. They are removable and reusable.
The spring-locking action and the resilience of the washer provide a firm assembly but cushion the shock of tightening, so that fragile components are not broken or damaged. This minimises distortion of sheet metal or the breaking of fragile plastic or ceramic parts during assembly. SR375011 is very popular.

Typical applications of washer type Self-Threading Nuts include plastic panels, ceramic products and motor vehicles.

FLAT ROUND PUSHNUTS - PUSH ON FASTENERS
This Flat Round Pushnut is a very cost effective option. This fastener provides a good balance between maximum holding strength and reasonable push on force. Pushnuts can be applied with great speed, as pushing on (especially with an air hammer) is much faster than running down nuts. 
These fasteners are especially suitable for products shipped in knock-down form.they are quite similar with the starlock washers.

• Quick and easy to install
• Economical
• Good for products in knock-down form
• Shock resistant
• Distortion resistant
• Multiple sizes

Typical applications for these push on nuts include electronics, medical equipments and electric vehicle,general machinery etc.
