• Cross recessed truss head tapping screw.
• Since the seat surface is large, it has an effect to prevent the seat surface from collapsing.
• The mating member must have a specified bottom hole.
• Made of iron with UNIQLO plating (light blue color) to improve corrosion resistance.
• The head is painted brown.
• Used when fastening to thin steel plates.
• Tighten the steel plate (thinner than the pitch of the screw) with the specified bottom hole while self-tapping.
