Three-Hole Manganese Steel Spring Clips
Three-hole manganese steel spring clips are stamped metal components designed for clamping, retaining, mounting and positioning applications.
With their elongated strip design, punched holes and formed spring section, these clips provide reliable elastic holding force — ideal for automotive sun visors, garage remote holders, AC equipment and panel fastening.
SEME Hardware manufactures custom three-hole spring clips from customer drawings, samples or specifications.
What Is a Three-Hole Spring Clip?
A three-hole spring clip features three punched holes along its flat section and a formed spring section that generates elastic retaining force.
The three holes add extra versatility — use them to hang small items (keys, air fresheners), attach a safety lanyard to prevent the remote from dropping, or optionally secure with screws when used in fixed panel applications.
For sun visor mounting, the clip simply slides onto the edge — the spring steel provides a firm, vibration-resistant grip without any tools, screws or adhesives.
Key customizable parameters include:
Length, width and material thickness
Hole diameter and spacing
Bend angle and spring opening
Spring force
Material and hardness
Surface treatment
Manganese Steel for Reliable Spring Performance
Manganese spring steel (e.g. 65Mn) is selected for its combination of high tensile strength, good elasticity, wear resistance and cost-effectiveness — ideal for repeated-loading spring clip applications. Material grade, hardness and heat treatment are selected per application.
Typical Dimensions & Tolerances
| Parameter | Typical Range | Tolerance |
|---|---|---|
| Length | 20 – 120 mm | ±0.1 mm |
| Thickness | 0.3 – 2.0 mm | ±0.03 mm |
| Hole diameter | Ø2 – Ø8 mm | ±0.05 mm |
| Hole spacing | 10 – 80 mm | ±0.1 mm |
| Formed height | 3 – 30 mm | ±0.15 mm |
Tighter tolerances available for OEM projects per approved drawing.
Common Applications
Automotive — sun visor clips (tool-free edge mounting; holes for accessory hanging or safety tether), interior trim retention, remote control holders, cable retention
Garage & Home — garage remote holders, panel retainers, mounting brackets
HVAC & AC — panel clips, filter retention, wire retention
Industrial — component positioning, cable management, vibration-resistant assemblies
Manufacturing Process
Three-hole spring clipsare produced through: material selection → precision stamping → hole punching → bending & forming → heat treatment (if required) → surface treatment (zinc / nickel / black oxide / powder coating / passivation) → quality inspection.
Inspection covers dimensions, hole position, surface condition and spring force when required.
Custom Spring Clips & OEM
We customize dimensions, spring force, material (65Mn, stainless 301/304/316, carbon spring steel, brass), surface finish and mounting configuration to your assembly.
Standard vs. Custom:
| Standard | Custom | |
|---|---|---|
| Dimensions | Fixed | Customized |
| Material | Limited | Application-specific |
| Spring force | Fixed | Optimized |
| OEM drawing | Unsupported | Supported |
For OEM projects, custom clips are designed around your assembly — not the other way around.
