BiSeal 0630 is a wax based material designed to seal sheet metal holes upon installation of the coated fastener. Highly effective on self-tapping screws in thin metal where typical sealants would not have enough thread engagement or material thickness to properly seal.

How it Works

BiSeal 0630 is factory pre-applied below the head of the fastener and arrives dry to the touch and ready for use. During installation of the fastener, the material collects in the thread path and under the head of the fastener to close off any openings that may allow the passage of fluids or contaminants. Because BiSeal is a non-reactive wax, it requires no cure time and seals immediately on assembly.


Effective Sealing

BiSeal 0630 seals against air, moisture, and environmental contaminants.

Full Seating Torque

Unlike underhead washers which lower clamp load, Biseal can be seated at the recommended torque.


Heavy body thickness and toughness make BiSeal effective on larger gaps made from self-tapping fasteners.


The non-volatile content of BiSeal 0630 more than 99 percent by weight.

Paint Staining

BiSeal 0630 will not discolor or stain surrounding areas when exposed to paint production systems.

Heat Resistant

BiSeal 0630 retains its original shape and will not flow or break down when exposed to 1 hour of dry heat at 135C.


  • Saves Time: Fasteners coated with BiSeal 0630 can be automatically fed through standard feeding devices – speeding up your process and improving productivity.
  • Saves Money: The bulk pre-application of BiSeal 0630 to fasteners costs less than other forms of fastener sealing applications.
  • Quality Control: Pre-Applied BiSeal 0630 fasteners are coated to specification, ensuring consistent performance.
  • Reliability: BiSeal 0630 replaces costly O-Rings that can be torn during installation.


  • Biseal 0630 requires no lead threads.
  • Indefinite on part life under ideal storage conditions [+40°F (+4°C) to +90°F (+32°C)], but re-certification must occur once a year.
  • As with all our pre-applied products, ND Industries can apply BiSeal 0630 onto your fasteners at any one of our regional service centers, or we can supply you with fasteners that contain a pre-applied Biseal 0630.
