Rhinails
Rhinails High Carbon Steel Divergent Point Staples are high-strength 4K series narrow crown fasteners engineered for hardwood furniture frames, security wire mesh, and heavy-duty upholstery.
Manufactured from quenched high carbon steel with an outer crown width of 5.60mm, 1.20mm wire diameter (1.27x1.04mm flat wire), and leg lengths from 6mm to 19mm.
Featuring razor-sharp divergent chisel points and up to 40g/m2 rust-resistant galvanizing, they drive smoothly into dense hardwoods without bending or leg buckling.
Looking for Factory-Direct High Carbon Steel Sharp Staples? Wholesale pricing from 406K to 419K. Direct manufacturer supply with fast worldwide dispatch. |
Engineered for dense hardwoods, tough upholstery backing, and security window screens:
High Carbon Core Hardness: Heat-treated high carbon steel prevents staple bending and buckling in dense timbers.
Divergent Chisel Points: Knife-edge sharp tips splay outward upon driving, creating a mechanical dovetail lock.
Heavy Rust Protection: Galvanized zinc coating up to 40g/m2 resists corrosion, moisture, and warehouse humidity.
Jam-Free Pneumatic Feeding: Precision flat wire and high-bond glue collation ensure smooth cycling in 4K air staplers.

Standard low-carbon wire staples frequently bend when driven into knotty hardwoods or tough plastic rattan. Rhinails high carbon sharp staples provide unyielding drive power:
Unmatched Hardwood Penetration: High carbon alloy core drives straight through oak, beech, ash, and kiln-dried framing without leg deformation.
Divergent Mechanical Lock: Angled chisel points spread outward as they penetrate, dramatically increasing pullout resistance under dynamic strain.
Cleaner Fiber Cut: Symmetrical sharp tips cleanly slice through fabric, synthetic wicker, and wood fibers without unsightly surface tearing.
Lower Air Consumption: Sharp cutting edges require less tool air pressure (4-7 bar), reducing compressor wear and operator recoil fatigue.
40g/m2 Zinc Protection: Uniform galvanization prevents surface oxidation in unheated manufacturing plants and humid coastal warehouses.
Controlled Metallurgy: Continuous furnace quenching and tempering balance high Rockwell hardness with impact toughness.
Precision Flat Wire: 1.20mm round wire cold-flattened to 1.27mm width and 1.04mm thickness for consistent crown rigidity.
Industrial Packaging: Moisture-barrier inner boxes and heavy-duty 20-box master cartons protect coils from transit damage.

Q: What is the difference between high carbon steel and standard staples?A: High carbon steel undergoes quenching and tempering, providing high hardness and rigid column strength to pierce dense hardwoods without bending. |
Q: Which staple guns are compatible with 4K sharp leg staples?A: Compatible with all standard 4K series pneumatic staple guns (such as 425K and 440K air nailers), BeA 90 series, and equivalent narrow crown pneumatic upholstery tools. |
Q: How do divergent sharp chisel points improve joint strength?A: Symmetrical angled cutting points slice wood fibers cleanly and spread outward inside the timber, locking the staple in place against withdrawal tension. |
Q: What is the packaging standard and MOQ?A: Packed 4800 to 4964 pcs per inner box, 20 boxes per master carton (gross weight 11.1kg to 30.0kg). Neutral MOQ is 50 cartons; custom OEM box MOQ is 100 cartons. |
Q: Can you supply matching 4K pneumatic staple guns?A: Yes. Rhinails manufactures commercial grade 4K pneumatic staple guns. We can ship matching tools and staple fasteners together in one shipment. |
