Features

Indented Hex Washer Head provides a broad bearing surface to distribute load, reduces pull-through on thin gauge metal, and supports flush seating during installation.

Unslotted Drive uses an internal hex interface for consistent torque transfer and compatibility with hex drivers, improving repeatability in automated and manual assembly.

Self tapping thread forms its own mating threads in sheet metal, eliminating the need for pilot holes or nuts and enabling rapid field or production-line assembly for thin to mid gauge materials.

Finish: Zinc Plated Bake delivers corrosion resistance and durable appearance, extending service life in interior environments and moderate exposure scenarios.

Use cases Ideal for fastening steel panels, enclosures, control boxes, and metal cabinets where a secure, torque-stable connection is required and pre-drilled pilot holes are standard practice.
