Blind Nut with Four Prongs Carbon Steel Grade 4.8 Zinc Plated

Preventing glue infiltration: The sealed top effectively prevents the glue applied during installation from flowing into the threaded holes, ensuring smooth screw insertion later.

Anti-particle blockage: Prevent wood chips, paint, dust, etc. from entering the internal thread area.

Friendly coating: When performing surface coating after pre-drilling the nuts, the blind head structure can prevent the coating from entering the threads.

Precise positioning: The bottom plane of the blind head provides a uniform force-bearing surface. After pressing in, it aligns with the bottom surface of the substrate.

Four prongs are symmetrically distributed: When pressed in, the four barbed prongs spread outward, and after embedding into the substrate, they form four independent anchoring points.

High tensile and pull resistance: For the M6 specification, the tensile and pull resistance in MDF substrate can reach 800 - 1200N.

Excellent torsion resistance: After all four claws are inserted simultaneously, it effectively resists the torque generated when the bolt is screwed in, preventing the nut from rotating.

Barb design: Claw tip with barbs, which cannot be pulled out in the reverse direction after installation, ensuring permanent anchoring.

The material is made by cold heading from high-quality carbon steel, and the 4.8-grade strength fully meets the general load requirements for furniture, display stands, etc.

The hardness is moderate, and it is not likely to deform during the pressing installation process.

The thread strength is reliable and it is unlikely to break easily during normal use.

If you need a higher level of intensity, you can purchase the 8th-level product.

Blue-white zinc coating: Uniformly shiny. Salt spray test for 24-48 hours meets the rust prevention requirements for indoor furniture.

Optional yellow zinc / colored zinc: Superior rust prevention performance, suitable for humid environments

Environmental protection technology: Compliant with RoHS standards, non-toxic and harmless

Uniform inside and outside: The coating covers both the inner and outer surfaces, including the interior of the threads.

The threads are precisely tapped after cold heading, with a thread accuracy of 6H.

The gauge block inspection was passed and the fit was smooth.

The thread strength is compatible with the main body and is durable and long-lasting.
