Uxcell 316 Stainless Steel Thread Adapters Sleeve Reducing Nut, 10 Pcs M6 x 1.0 Male to M4 x 0.7 Female Repairing Insert Nut Screw Reducer Conversion Fastener 10mm

Repair insert nuts are essential components in industrial fastening systems and are commonly used in conjunction with screws or bolts. They serve as effective solutions for repairing damaged or incorrectly threaded holes. These versatile repair nuts find extensive application across various manufacturing sectors, including aviation, automotive, electronic communications, computers, lighting fixtures, mechanical equipment, radiators, etc.

Advantage

Constructed from 316 stainless steel, the repair insert nuts have better stability, corrosion resistance, oxidation resistance, strength, and heat resistance, and does not rust when working in humid environments compared to 303 stainless steel. Even in challenging environments, they maintain optimal functionality and longevity.

Instruction

The surface of these thread-reducing nuts is smooth, with deep and clear threads that distribute force evenly. To facilitate installation and removal, each thread-reducing nut has a slot at the top for accommodating a flat head screwdriver, making it easier to screw them in.

Note

If there is a stripped M3 thread and you wish to continue using an M3 thread, you can use this method to expand the M3 thread to M5, and then recover it back to M3 using the repair nut. Reducing the diameter and utilizing stainless steel material, will make the M5 thread stronger.
