Cross-Recessed Pan Head Screw
Caution
- Please note that if the mating part is to be prepared by the customer, it will not fit unless it is over-tapped according to the standard.
- Since hot-dip galvanizing results in a very thick coating, please select a product with the same surface treatment for the mating component.
- The product images are representative only. Specifications may vary by part number, including shape and color.
*"Other special treatment" under "Surface treatment" refers to the following specifications.
3W-ZEC: ZEC coat - trivalent white undercoat
3B-ZEC: ZEC coat - trivalent black undercoat
AEN: ZEC Coating - Zinc Plating Base
