The Hardware Press-fit Clasp Assembly is a one-piece combined part that both fixes and locks: a rigid body carries structural load while an elastic arm provides the snap-lock action. The body is normally SPCC and the elastic arm SUS301, and the two materials can be specified independently. Body thickness is 1.2 mm and elastic-arm thickness 0.8 mm, adjustable separately. The combined locking tension is at least 55 kg, and the elastic arm survives 300,000 cycles without fracture. Overall coaxiality is held within 0.1 mm so the assembled clasp stays aligned, and the whole part is nickel plated 8 μm to reach 120 h salt spray without rust points, with gold, zinc or blackening finishes available.
A combined clasp-and-locating part is harder to get right than a single-material stamping because two materials with very different stiffness must move as one. Separately controlling the rigid body and the elastic arm - and holding coaxiality to ≤0.1 mm - is what lets the press-fit stay true while the arm still flexes to lock, avoiding the common failure where a mixed part binds or drifts. The ability to pair different materials and thicknesses for body and arm lets a buyer tune retention force against rigidity in a single integrated component instead of sourcing two separate parts.

Applications
Quick-release equipment latching - the integral elastic arm locks a cover or drawer on press-fit while the rigid body keeps it aligned, replacing two separate parts.
Repeated service-access hardware - 300,000-cycle arm fatigue keeps the clasp working through frequent opening and closing.
Corrosion-prone assemblies - the 8 μm nickel finish and 120 h salt-spray resistance suit housings exposed to moisture or cleaning.
Customization
Body and elastic-arm materials and thicknesses chosen independently, integrated or split combined structure, locking tension and fatigue life, coaxiality tightening, plating (nickel / gold / zinc / blackening); developed from customer drawings and samples; OEM / ODM.
Packaging & Transportation
Combined clips are PE-bagged in controlled quantities to protect the plated finish and prevent arm distortion, then cartoned with pallet option; dedicated pre-pack inspection, 100% depending on the product. Trade terms: EXW, FOB or DDP.
FAQ
Q: Can the body and elastic arm be made of different materials?
A: Yes. The rigid body and elastic arm can be specified separately - for example heavy-duty carbon steel body paired with a beryllium-copper arm - and their thicknesses adjusted independently.
Q: How long does custom sample development take?
A: It depends on complexity: simple samples take 3–5 days and more complex combined structures 5–10 days.
Q: Do you accept third-party inspection?
A: Yes, we accept third-party inspection, and a dedicated inspector checks production quality.
