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 Elastic Steel Ball Nut Introduction
Elastic Steel Ball Nut, also known as spring ball T-slot nut, is a specialized fastener designed for industrial aluminum profile assembly. It is manufactured from 316 stainless steel, composed of a curved nut body, built-in spring and steel ball assembly.
316 stainless steel provides outstanding corrosion resistance, salt spray resistance and chemical resistance, making it suitable for coastal, wet and corrosive working environments. The internal spring pushes the steel ball outward. When inserted into the T-slot of aluminum extrusion profiles, the steel ball presses against the inner wall of the profile groove to hold the nut in position. The nut can slide freely along the T-groove to the required mounting position before tightening. When matched with hex socket cap screws, the preloaded steel ball and spring structure provides positioning force to prevent accidental shifting and loosening caused by vibration.
This nut is easy to install without welding or auxiliary tools. It features flexible sliding, reliable positioning and good
reusability. Widely used in industrial aluminum profile frames, automation equipment racks, marine equipment, chemical machinery, safety guardrails and workstation assemblies. Multiple thread specifications are available to match different aluminum profile series.

Stainless Steel Fastener 316 Elastic Steel Ball Nut Product Processing
1.Raw Material Inspection & Precision Blanking:
Select 316 stainless steel bar for nut body, 316 stainless steel spring wire and 316 stainless steel ball as raw materials. Conduct incoming material inspection, including spectrometer chemical composition analysis, hardness and tensile strength testing to verify compliance with ASTM A240 standard. Visual inspection is performed to screen raw materials with surface pits, oxidation spots, cracks or internal inclusions. Cut the stainless steel bar into fixed-length blanks by precision sawing according to drawing dimensions, and remove cutting chips and oil contamination to obtain qualified semi-finished blanks for subsequent forming.
2.Cold Forging & Machining:
3.Cavity Finishing & Spring and Steel Ball Preparation:
4.Spring & Steel Ball Assembly & Pre-test:
5.Surface Finishing & Multi-dimensional Performance Testing:
6.Final Full Inspection & Moisture-proof Packaging:
2.Cold Forging & Machining:
Carry out room-temperature cold forging on 316 stainless steel blanks with dedicated forging moulds to form the curved T-slot nut body profile. Cold forging optimizes internal metal grain flow to enhance the mechanical strength of the nut. After forging, perform tapping to process standard internal threads, strictly controlling thread pitch, tooth profile and dimensional tolerance to guarantee smooth matching with mating screws. Machine the reserved small hole cavity on the nut body for assembling spring and steel ball, and monitor hole size and position accuracy during machining.
3.Cavity Finishing & Spring and Steel Ball Preparation:
Precision reaming and deburring for the spring-ball mounting cavity on nut body to eliminate sharp edge burrs that may scratch the spring. Cut 316 stainless steel spring wire into specified length and wind into compression springs, then carry out spring heat setting treatment to stabilize elastic performance. Select 316 stainless steel balls with high roundness, inspect surface finish and diameter tolerance, and remove defective balls with scratches or deformation.
4.Spring & Steel Ball Assembly & Pre-test:
Assemble the compression spring and stainless steel ball sequentially into the pre-machined cavity of nut body. Ensure the spring can push the steel ball to protrude outwards smoothly, and the steel ball will retract into the cavity under external pressure. Conduct manual compression test piece by piece to check the telescoping performance of steel ball. Reject products with stuck ball, insufficient spring force or ball falling off.
5.Surface Finishing & Multi-dimensional Performance Testing:
Carry out fine tumble polishing to clear surface oil stains, metal particles and tiny burrs. Complete a full set of performance tests: thread fit test to verify screw assembly smoothness; steel ball telescoping cycle fatigue test; vibration anti-shift test; salt spray corrosion test to validate the anti-corrosion performance of 316 stainless steel. Isolate and sort out all non-conforming products.
6.Final Full Inspection & Moisture-proof Packaging:
Implement full final inspection against engineering drawings, including overall dimension check, appearance inspection, thread integrity verification and steel ball elastic rebound function test. Qualified products go through ultrasonic cleaning and hot air drying to remove residual dirt. Pack finished nuts into moisture-proof bags with desiccants, mark product specifications, batch number and material grade on packaging labels, to protect parts from moisture and mechanical damage during storage and ocean transportation.
