What Stands Out
High Grade Strength
Made from 10.9 grade alloy steel, these screws offer superior tensile strength and durability, making them ideal for heavy-duty applications.
Countersunk Design
The flat head design allows for a flush finish, perfect for sleek installations while preventing snagging and enhancing aesthetic quality in projects.
Value Pack Quantity
With 100 pieces included, this bulk pack provides excellent value, ensuring you have enough screws for multiple projects and reducing the need for frequent repurchases.
