Cap Nuts Are Used as Follows
①
The cap nut and stainless steel hexagon slotted nut are equipped with a split pin, which is matched with the screw with a hole bolt. It is used to withstand vibration and alternating loads, and it can prevent the nut from loosening and coming out.
②
A cap nut with an insert. The insert relies on the tightening nut to tap the internal thread, which can prevent loosening and has good elasticity.
③
The cap nut has the same purpose as the hexagon nut. It is characterized in that the main nut is not easy to slip with a wrench during assembly and disassembly, but only a spanner wrench, a dead wrench, a dual-use wrench (opening part), or a special square hole sleeve can be used. Install and remove with a barrel wrench. Mostly used on rough, simple components.
④
The cap nut can be used in the case where the end of the bolt needs to be capped.
⑤
Cap nut can be used for tooling.
⑥
The cap nut and ring nut can generally be disassembled by hand instead of using tools, and are usually used in situations where frequent disassembly and low force are required.
⑦
The cap nut is mainly used for fixing tires, front, rear, left and right on tires and front and rear axles of automobiles, tricycles, electric vehicles, etc., and can also be used to fix road lamp bases and machinery that are often exposed to sunlight and rain. Device.
⑧
The cap nut is used in conjunction with the hexagon nut to play a role of locking the hexagon nut, and the effect is better. One side of the welding nut is used for welding to the thin steel plate with holes, and then connected to the bolt.
⑨
Cover nut is suitable for high-strength fasteners, mechanical fasteners, furniture fasteners, vehicle fasteners, turning special-shaped parts, cold-headed special-shaped fasteners, double-headed foot U-shaped Wire, building decoration fasteners, and other types of fasteners can also be used in basic engineering, auto and motorcycle accessories, light industry, machinery, furniture, hardware tools, building decoration and so on.
⑩
The surface of the cap nut generally needs to be treated, including some surface treatment processes such as galvanizing, nickel plating, chrome plating, and Dacromet to make it more rust-proof and increase the service life of the fasteners. In the surface treatment process, chrome plating is the best process. The chrome-plated product not only has a smooth and bright surface, but also has a longer rust and corrosion resistance, which is comparable to stainless steel.
Frequently Asked Questions (FAQ)
Q: What standards and sizes are available for these cap nuts?
Our cap nuts conform to global standards including GB, BS, DIN, and ANSI. We offer sizing options ranging from GB M1-M100, BS 1/8-1, and ANSI 4#, 6#, 8#, 10#, 12#.
Q: What materials and strength grades are used?
They are manufactured from high-quality Stainless Steel and Carbon Steel. Strength grades available include 4.8, 8.8, 10.9, and 12.9.
Q: How do cap nuts prevent loosening under vibration?
Cap nuts can be paired with split pins and slotted hexagon bolts to withstand vibration and alternating loads. Additionally, cap nuts with inserts tap internal threads to prevent loosening with excellent elasticity.
Q: What are the typical applications of cap nuts?
They are widely used in equipment fixing, steel structures, street lights, traffic signs, boiler installations, auto parts, furniture, and heavy machinery requiring protection for exposed bolt ends.
Q: Which surface treatment offers the best corrosion resistance?
While we offer galvanizing, nickel plating, and Dacromet, chrome plating is the premium choice. It provides a smooth, bright finish and offers rust and corrosion resistance comparable to stainless steel.
