Finding the perfect fit for your open-type red dot sight can be surprisingly frustrating. You have the sight, you have a compatible mount, but the standard screws that came with either component often fall short in one of two ways: either they are too short to firmly engage the threads, leaving the sight loose and insecure, or they are too long, protruding from the bottom of the mount plate, interfering with the host weapon or simply looking unsightly. You are left wishing for a length that is just a little different?a few millimeters more or less that would make everything perfect.

This is precisely the problem that this carefully curated set of M3 flat head screws solves. Recognizing that standard off?the?screw lengths, namely M3x8 and M3x10, are often not ideal, this set provides a full range of non?standard lengths in precise 0.5mm increments from 7mm all the way to 9mm. That means you get M3x7, M3x7.5, M3x8.5, and M3x9?sizes you simply will not find in a typical hardware kit. But the set does not stop there. It also includes a longer 10mm screw for those uncommon mounts that have extra thread depth, giving you even more flexibility.

Whether you need a screw that sits perfectly flush with the bottom of the mount plate or one that reaches just deep enough to hold the sight securely without bottoming out, this assortment has you covered. Each screw is a hex socket (Allen) head flat head screw, designed to sit neatly into the countersunk holes of most red dot sights and their mounts.

Please note two important compatibility restrictions. First, these screws are M3 thread and cannot be used if your dot sight mount has an M4 female thread. Second, they are intended for sights that are attached using conventional socket head screws; they will not work with red dot sights that employ cap bolts or other proprietary fastening systems.

The complete set includes six distinct lengths in a single convenient package: M3x7, M3x7.5, M3x8, M3x8.5, M3x9, and M3x10. Stop compromising with ill?fitting screws. With this set, the ideal length for your red dot sight and mount combination is always at hand.

Key Features

• This set of M3 flat head screws is designed to attach open-type red dot sights to compatible mounts.
• With standard screws, you often find that the screw length is either too short to secure the sight properly, or too long so that the tip protrudes from the mount plate?leaving you wishing the length was just a little different.
• This product solves that problem by offering non?standard screw lengths in 0.5mm increments from 7mm to 9mm (note that M3x8 and M3x10 are existing standard sizes, so the truly unique lengths are 7mm, 7.5mm, 8.5mm, and 9mm).
• A longer 10mm screw is also included, making the set compatible with mounts that have extra thread depth.
• Please be aware that these screws cannot be used if your dot sight mount has an M4 female thread, nor can they be used with red dot sights that employ cap bolts.
• The complete set contains six hex socket head screws in the following lengths: M3x7, M3x7.5, M3x8, M3x8.5, M3x9, and M3x10
