Self-Tapping Screws Manufacturer

Global Fasteners Exports is a trading and export company: its self-tapping screws are manufactured by partner factories, with batch testing and mill test certificates available on every order.

We are a trading and export company, and our products are manufactured by partner factories. Our role is to control quality from raw material through to finished, inspected product — cold-forging, hot-forging, or precision machining at those factories, with batch testing against whichever standard your project specifies.

This is the role that matters most when a buyer needs traceability: a heat number on a mill test certificate, dimensional inspection records, and a documented process from raw bar stock to finished, packed product. Buyers should ask to see this documentation rather than take quality claims at face value.

The distinction between self-tapping and self-drilling trips up more first-time buyers than almost any other spec in this catalog. Self-tapping screws form threads into a pre-existing hole and rely on the installer (or a pre-drilling step) to get that hole right; self-drilling screws carry their own drill-point tip and skip the pre-drilling step entirely, at the cost of a slightly more expensive part. Ordering the wrong one for the job either wastes the drill-point cost or leaves installers drilling holes that should have been unnecessary.
