Products Description
Stainless Steel 316 Introduction
316 is chrome-nickel austenitic alloy. It also contains molybdenum which increases general corrosion resistance,improves
resistance to pitting from chloride ion solutions, and provides increased strength at high temperatures.316 also provide excellent fabricability and formability. It is also called Marine Grade Stainless Steel.

Stainless Steel Fastener 316 Shrapnel Nut Introduction
Shrapnel Nut, also known as spring slot nut or T-slot spring nut, is a specialized fastener designed for aluminum profile
assembly. It consists of a rectangular nut body and an integrated spring shrapnel, manufactured from 316 stainless steel.
316 stainless steel material delivers excellent corrosion resistance, salt spray resistance and high-temperature performance,suitable for harsh environments with moisture, chemical media and coastal atmosphere. The built-in spring shrapnel holds the nut inside the T-groove of aluminum extrusion profiles. It can slide freely along the profile groove to the required mounting position before tightening. When matched with hex socket screws, the elastic shrapnel provides continuous preload to resist loosening caused by vibration and shock.
This nut requires no welding or pre-installation tools. It features convenient positioning, stable clamping force and high
reusability. Widely applied in industrial aluminum profile frames, automation equipment racks, marine equipment, chemical machinery, cabinet frames, workstations and mechanical guardrail assemblies. Multiple thread sizes are available to fit different aluminum profile specifications.

Stainless Steel Fastener 316 Shrapnel Nut Product Processing
1.Raw Material Inspection & Precision Blanking:
Select 316 stainless steel solid bar for nut body and 316 stainless steel spring strip for integrated shrapnel. Perform incoming raw material inspection, including spectrometer chemical composition analysis, tensile strength and hardness testing to confirm compliance with ASTM A240 standard. Visual inspection is implemented to detect surface pits, oxidation marks, internal inclusions and cracks. Cut the steel bar and spring strip into fixed-length blanks by sawing and shearing strictly following drawing dimensions, and clean cutting chips to prepare qualified semi-finished blanks for subsequent forming.
2.Cold Forging & Thread Machining:
3.Shrapnel Precision Stamping & Bending:
4.Component Assembly & Integrated Deburring:
5.Surface Finishing & Multi-dimensional Performance Testing:
6.Final Full Inspection & Moisture-proof Packaging:
2.Cold Forging & Thread Machining:
Conduct room-temperature cold forging operation on 316 stainless steel blanks with professional forging moulds to form the rectangular outline of the nut body. Cold forging optimizes the internal metal grain structure to improve mechanical strength. After forging, perform tapping to process standard internal threads. Strictly control thread pitch, major diameter and tooth profile to guarantee smooth matching with mating screws. Machine the reserved assembly notch on the nut body for shrapnel installation, and monitor dimensional tolerance during processing.
3.Shrapnel Precision Stamping & Bending:
Use high-precision progressive stamping dies to punch, blank and bend the 316 stainless steel spring strip. Form the standalone shrapnel into the designed curved elastic structure. Adjust stamping pressure and bending angle to ensure stable elastic deformation and long-cycle fatigue resistance. Remove sharp edge burrs from stamped shrapnel parts by micro-deburring, avoid scratching operators or aluminum profile grooves during assembly. Random sampling is carried out to test spring rebound performance. No ball or pellet component is used in this design.
4.Component Assembly & Integrated Deburring:
Assemble the stamped standalone 316 shrapnel into the pre-machined notch of nut body, ensure the shrapnel is tightly fixed and cannot fall off. Carry out integrated tumbling deburring treatment for the assembled shrapnel nut, to eliminate tiny burrs on thread teeth, outer contour and shrapnel edges. Manually test the elasticity of shrapnel one by one, confirm that the shrapnel can compress and rebound smoothly without stuck or permanent deformation.
5.Surface Finishing & Multi-dimensional Performance Testing:
Implement fine surface polishing to remove oil stains and metal particles on the surface. Conduct a series of performance tests: thread fit test to check screw assembly smoothness; spring fatigue test to verify elastic stability after repeated compression; vibration anti-loosening test; salt spray test to validate the natural anti-corrosion property of 316 stainless steel. All non-conforming products will be picked out and isolated.
6.Final Full Inspection & Moisture-proof Packaging:
Carry out full final inspection in accordance with engineering drawings, including overall dimension check, appearance inspection, thread integrity verification and shrapnel rebound function test. The qualified products go through ultrasonic cleaning and drying to remove residual dirt. Pack finished nuts into moisture-proof packaging bags with desiccants, mark product specifications and batch number on the package, to avoid moisture and mechanical damage during storage and ocean transportation.
