Zenitco M5x9 Screw
Genuine Zenitco | Countersunk flat-head slotted screw | Steel | M5 x 9 mm
In short: a genuine Zenitco M5x9 screw - a steel fastener with a countersunk (flat) head and a straight slot. It is the standard mounting screw used on many Zenitco brackets and handguard kits, so it is the exact spare to keep on hand if you lose or strip one during installation.
Overview
A genuine Zenitco M5x9 screw: countersunk flat head with a straight slot, machined from 40X steel.
This is the fastener Zenitco uses throughout its rails and Bazis accessories, and the 9 mm length is one of the two that appear most often. Kits normally ship with the right ones, so this listing exists for the screw that goes missing during a rebuild.
Use the correct length. A screw that is too long bottoms out before it clamps; too short and it strips the thread in an aluminum part. The straight slot is deliberate - a coin or a knife back will turn it when no driver is at hand.
Compatibility: an M5 x 9 mm countersunk slotted screw. It is the factory fastener for many Zenitco mounts and handguard kits (for example the Sport-series handguard brackets). Check that your part uses an M5x9 flat-head screw before ordering.
