Choosing Screw Size For Rmr Mos Mounting Plates

When mounting a Trijicon RMR to a Glock MOS, it is important to note that the screws that come with the RMR are not compatible with the MOS. Therefore, it is necessary to purchase a separate mounting screw kit that includes the correct screws for attaching the MOS plate to the slide, the RMR to the MOS plate, and the MOS cover to the slide. The correct screw sizes for the Glock MOS and Trijicon RMR are 6-32 x .385 for the RMR mounting screws and M3 x 0.5 x 8mm for the MOS cover plate and MOS adapter plate screws. These screws are available from various retailers, including Battle Werx and Amazon, and it is important to ensure that the correct screw lengths are selected for the specific firearm model.

RMR mounting screws for Glock MOS slides

If you are mounting an RMR to your Glock MOS, you will need to purchase a kit of screws separately. The screws that come with the RMR are not compatible with Glock MOS models.

The Trijicon RMR Replacement Screw Kit for Glock MOS includes:

• Two 6-32 x .385" RMR mounting screws (T-15 Torx)

These screws are custom-length CAMCAR brand flat socket cap screws (US-made) that provide maximum thread depth in the MOS adapter plate.

You can also purchase individual replacement screws for your RMR from Primary Machine. Their website specifies that the shorter screw is to be used on the ejection (right) side of the slide, while the longer screw is used on the left side.

It is important to note that the Trijicon RMR ships with two long screws that will not work with the Glock MOS. Therefore, it is necessary to purchase the correct screws separately to ensure a secure fit.

Screws for mounting adapter plates

When it comes to selecting the right screws for mounting adapter plates, several factors come into play to ensure a secure and stable installation. The type of screws used will depend on the specific application, whether it's for furniture, electronics, or something else entirely. Here are some considerations and guidelines to help you choose the appropriate screws:

Understanding Screw Types

• Material: Screws come in various materials, including metal, steel, and nylon. The choice of material depends on factors such as the weight-bearing requirements, environmental conditions, and compatibility with the mounting surface.
• Head Type: The head type of a screw refers to its shape and recess type. Common types include flat head, round head, and hex head. The head type should match the type of screwdriver or tool required for installation.
• Thread Type: Screws with fine threads are suitable for softer materials like wood, while coarse threads are better for harder materials like metal.

Standard Screw Sizes for Adapter Plates

• Metric: Metric screws are specified by diameter and length, such as M3, M4, or M5, followed by the length in millimeters. For example, a "M4x10" screw has a diameter of 4 millimeters and a length of 10 millimeters.
• Imperial: Imperial screws are measured in inches and typically use a number and gauge system, such as #6-32 or #8-32, indicating the diameter and thread count per inch.

Examples of Screw Applications

• Furniture: Mounting plates for furniture legs often use screws to attach the plate to the leg and secure it to the furniture body. Standard screw sizes for furniture mounting plates include M8 for legs and cylindrical plate nuts.
• Electronics: When mounting adapter plates for electronics, such as TV mounts or camera tripods, ensure you have the correct screw size to match the thread on your device. For example, a standard 1/4"-20 camera screw is commonly used for DSLR cameras.
• Walls and Ceilings: Adapter plates for wall or ceiling mounting may use screws with anchors to ensure a secure hold. The screw size will depend on the weight of the object being mounted and the type of wall or ceiling material.

It's important to refer to the manufacturer's instructions or specifications for your particular adapter plate to ensure you select the correct screw type and size. This ensures a safe and secure installation for your specific application.

Screws for mounting cover plates

When mounting cover plates, it is important to use the correct type and size of screws to ensure a secure fit and avoid damaging the plate or the firearm. The correct screws for mounting a cover plate to a Glock MOS will depend on the specific model of the firearm and the type of mounting system being used.

For a Glock MOS with a Trijicon RMR, the correct screws for mounting the cover plate are M3 x 0.5 x 8mm flat socket cap screws with a T-10 Torx Plus drive. These screws are typically included in a replacement screw kit specifically designed for the Glock MOS and Trijicon RMR combination. The kit may also include screws for mounting the adapter plate and the RMR itself. It is important to note that the screws that come with the Trijicon RMR are not compatible with the Glock MOS, so the correct screws must be sourced separately.

When purchasing screws for mounting cover plates, it is essential to consider the thread size, length, and drive type. The thread size and length will ensure compatibility with the mounting holes on the cover plate and the firearm, while the drive type will determine the type of screwdriver or bit needed for installation. In some cases, it may be necessary to modify the screws to achieve the correct length or thread depth.

Proper torque and thread locking are also critical factors when mounting cover plates. Over-tightening the screws can damage the plate or the firearm, while under-tightening can result in a loose fit. It is recommended to follow the manufacturer's instructions for torque specifications and to use thread-locking compounds, such as Loctite, to secure the screws and prevent them from backing out over time.

Overall, selecting the correct screws for mounting cover plates involves considering the specific firearm model, the mounting system, screw dimensions, and installation techniques. By choosing the right screws and following proper installation procedures, users can ensure a secure and reliable fit for their cover plates.

Screw kits for Glock MOS

If you're looking for a screw kit for your Glock MOS, there are a few options to consider. Firstly, it's important to note that the screws that come with the Trijicon RMR are not compatible with Glock MOS models. Therefore, you will need a separate screw kit for the attachment.
