Self Clinching Nuts

Features of Clinching Nuts

Nylon Insert Lock Nut:

Sheet Metal Rivet Nuts 300 or 400 series stainless steel self clinching nut vs rivet nut for sheet metal

M3M5M6 or Custom Self Clinching Nuts& Self Clinching Standoff:

Clinch Nut SS 304 is a set of thin plate special cold press fastening thread components designed for fast, secure, and welding free installation of metal sheet metal sheets. By embedding pressure into prefabricated holes, the material is locked in place through plastic flow. After installation, the surface is flat, the thread strength is high, and the seismic resistance does not fall off, making it suitable for automated mass production.

Standard type (CLA/CLS/CLSS) Self tightening nut metal: The most widely used, suitable for steel, aluminum and other sheet materials, providing high load-bearing capacity and anti rotation function.

Flush Nut self clipping blind and flush nuts: After installation, the nut is flush with the panel surface, suitable for panels with requirements for appearance and scratch resistance.

Stainless steel special type (SP/CLS-S/SPB) blind self clip nut: made of harder stainless steel, designed specifically for stainless steel sheets to prevent biting, micro/small specification type (CLA), floating/self-locking type, etc.

Core Features of self clinching nuts with nylon insert or sheet metal nuts and bolts:

High strength: Provides reliable load-bearing threads on thin plates, with excellent resistance to thrust and torsion.

Easy installation: fixed in one press, suitable for automated production, no post-processing required.

Space saving: After the nut is installed, it is basically flush with the board surface, does not occupy additional space, and has a clean appearance.

Reusable: The internal thread can be screwed in and out of the bolt multiple times, which is superior to directly tapping on thin plates.

Reliable performance: Through mechanical bite fixation, it can effectively resist vibration and impact, and has good anti loosening performance.

Diverse materials: Common materials include carbon steel (galvanized/nickel), stainless steel (304/316), etc;

Self clinching fasteners for sheet metal-nylon insert nut lock:

‌Item:Nylon Insert Self-Locking Fasteners Nut with Knurling PL PLC for Metal Panel

Surface Treatment:Zinc Plating,Plaining,etc

Material:300 series stainless steel or hardened steel.

Application:Thin Metal Sheet,Steel and Aluminum Sheets,etc

Self clinching flush fastener type F or F4:

‌Item:Self-Clinching Flush Fasteners - Type F or F4 - Metric & Inch

Surface Treatment:Zinc Plating,Plaining,etc

Material:300 Series Stainless Steel or Heat treated 400 Series Stainless Steel

Application: Thin Sheet Metal,Automotive Body Components,General Sheet Metal Assemblies,Etc.

Flush nuts are specifically designed to be installed into stainless steel sheets.

Self clinching fasteners - Self clinching stud:

‌Item:Thru-Hole Threaded Standoffs for Installation into Stainless Steel

These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.

Types SO4 standoffs are for installation into stainless steel sheets as thin as .040”.

Unthreaded standoffs are also available for spacing multi-panel assemblies.

Material: SO (Heat-treated Carbon Steel), SOS(300 Series Stainless Steel),SOA(Aluminum),SO4(Stainless Iron),etc.

Threading:Threaded & Unthreaded

Self clinching nut m6 stainless steel cls-m6-2 or CLS CLSS SS S Type:

‌Item:Self clinching nut m3 m4 m5 m6 or Custom

Material:300 or 400 Series Stainless Steel

Thread specifications: such as M2, M3, M4 or as per customer's request, need to be matched with matching bolts.

Applicable plate: Clearly define the material (steel, aluminum, stainless steel) and hardness range (such as HRB, HB) of the plate.

Plate thickness: according to the selected rivet nut specifications;

Installation hole size: refer to the specification table;

Notes:

(1) For maximum performance, we recommend that you use the maximum shank length for your sheet thickness

(2)This shank code not available for SP nuts.

(3) This thread size S nut, with a -2 shank code, can be instaled successfuly without the need to pre punch a mounting hole in    a separate operation.

Application: 

Automobiles and new energy vehicles: body panels, control boxes, battery packs, seat brackets, etc.

Electronics and communication: chassis, power supply casing, heat sink, metal casing of communication equipment, etc.

Home appliances and industrial equipment: various sheet metal cabinets, control panels, brackets, home appliance casings, etc

Working principle of SS 304 blind clip nut

Positioning: Place the self-locking nut into the pre punched thin plate, with its toothed or grooved side facing the plate.

Press in: Use a press to apply continuous axial pressure to the nut, rather than impact force.

Cold forming: Under pressure, the sheet undergoes plastic deformation, and the metal is squeezed into the annular groove on the outside of the nut body, forming a mechanical interlock.

Locking: After installation, the nut is permanently fixed on the board, and the surface of the opposite board remains flat and does not protrude.
