DrillTech 5.5mm Stainless Steel Self Drilling Screw (bi-metal) 100 Pack

Product Overview:

The DrillTech 5.5mm Stainless Steel Self Drilling Screw (bi-metal) is a type of screw designed for drilling through metal surfaces without the need for pre-drilling holes. This specific variant comes in a pack of 100 screws. The screws are made from stainless steel, which provides corrosion resistance and durability.

The size of the screws is 5.5mm in diameter. There are several length options available:

From 5.5 x 40 to 5.5 x 100
From 5.5 x 40 with washer to 5.5 x 100 with washer
The "5.5" refers to the diameter of the screw shaft in millimeters, and the numbers following "x" indicate the length of the screw in millimeters. The addition of a washer helps distribute the load and can provide a more secure attachment in certain applications.

These self-drilling screws are particularly useful for applications where drilling a pilot hole beforehand would be time-consuming or impractical. The bi-metal construction suggests that these screws are made from two different types of metal, potentially enhancing their drilling and fastening capabilities.

Key Features:

• Eliminates the need for pre-drilling.
• Suitable for metal surfaces.
• Available in various lengths and with washers for versatility.
• Convenient 100-pack for multiple applications.
