Overview
Self-piercing screws are high-performance fasteners designed to penetrate thin sheet metal without the need for pre-drilling. Unlike self-drilling screws, self-piercing screws do not remove material; instead, they displace it to form mating threads in thinner gauge metals.
Commonly used in automotive, appliance, HVAC, and light-gauge steel applications, self-piercing screws provide fast installation, high pull-out resistance, and reduced assembly time.
Offshore Milling & Sourcing supports bulk and factory-direct sourcing programs for self-piercing screws, serving OEM manufacturers, sheet metal fabricators, automotive suppliers, and industrial distributors requiring dependable high-volume supply and competitive pricing.
