Who it fits

Key specs explained for LGA 775 pins

Socket Compatibility: LGA 775

These pins are designed exclusively for Intel LGA 775 motherboards. You should verify your motherboard socket before purchasing. They will not fit modern LGA 115x or AM4 sockets. This compatibility ensures a secure fit for older cooling solutions. It is critical for maintaining proper thermal contact on legacy hardware.

Package includes: 12 heat dissipating plastic Push Screws

The pack contains twelve individual mounting pins. This quantity allows you to replace multiple broken units or keep spares on hand. Since CPU coolers often require four pins, this pack covers three complete installations. It provides a practical supply for maintaining older systems without needing additional purchases.

Material: high quality industrial grade plastic

The pins are constructed from durable industrial plastic. This material resists rust and corrosion, which is important for long-term stability. Plastic is lighter than metal alternatives, reducing stress on motherboard holes. It offers a reliable solution for securing heatsinks without conducting electricity or interfering with nearby components.

Weight: 0.99 ounces

The entire pack weighs less than one ounce. This low weight means the pins add negligible mass to your cooling assembly. It simplifies handling and installation, as you do not need to manage heavy components. The light packaging is easy to store in a toolbox or drawer for future repairs.

Design and build quality

According to the listing, these pins are constructed from industrial grade plastic. This material choice prioritizes light weight and durability over metal strength. You get twelve units per package, which provides enough spares for multiple builds or replacements. The small size allows for easy handling during installation. The design functions as a push screw, meaning you press them into place rather than threading them. This eliminates the need for tools during basic mounting tasks.

The weight is listed at 0.99 ounces for the entire pack. This low mass confirms the plastic construction. It is not a heavy metal component. The finish is described as rust free, which suits the indoor environment of most computer cases. The listing notes they are environmentally friendly, though this does not affect performance. You should view these as simple mechanical fasteners. They do not include any thermal interface material or adhesive.

Layout is straightforward. You receive twelve identical pins. There are no varied sizes or mixed components. This uniformity simplifies inventory management. You use them to secure CPU coolers to LGA 775 motherboards. The plastic body resists corrosion better than untreated metal in humid conditions. However, you must handle them carefully during installation. The push mechanism relies on friction. Ensure your motherboard holes are clean and undamaged for a secure fit. These are replacement parts, not primary mounting hardware for new builds unless specified by your cooler manual.

Setup and everyday use

Installing these pins requires no tools. You press each plastic rivet directly into the pre-drilled holes on your LGA 775 motherboard. The design relies on friction to stay in place. This method is significantly faster than threading traditional metal screws. You align your CPU cooler base with the four mounting points. Then, you push each pin firmly until it sits flush with the board surface. The industrial grade plastic construction ensures they hold their shape under pressure. You do not need to worry about cross-threading or stripping holes. This makes the process accessible even if you are new to hardware assembly. Once installed, these pins provide a stable foundation for your heat sink. They are rust-free and environmentally friendly, which helps maintain a clean interior. You can leave them in place for years without degradation. The lightweight nature of the plastic adds negligible weight to your system. If a pin ever breaks, you can easily replace it with another from the twelve included in the package. This availability is practical for older systems where finding exact replacements can be difficult. Note that these are installation pins only. They do not include the cooler itself or any other mounting hardware. You must have a compatible LGA 775 cooler to use them effectively. The small size allows for easy storage in a toolbox or component bag. You can keep a spare pack handy for future repairs or upgrades. This simplicity makes them a reliable choice for maintaining legacy hardware.

Before You Buy LGA 775 Pins

You need these pins only if your LGA 775 cooler mounting hardware failed. They replace broken plastic rivets or lost screws. You must verify your motherboard uses the LGA 775 socket. Modern CPUs use different sockets, so these will not fit. You do not need thermal paste for the pins themselves. However, you will still need high-quality thermal paste for the CPU heatsink interface. The cooler itself is a separate purchase. These pins are small, lightweight replacements. They fit alongside other LGA 775 specific accessories in our guide. You should check your cooler’s mounting bracket holes match this design. Keep the package sealed until needed. Dust can enter the plastic over time. Store them in a dry place. This part is purely mechanical. It does not affect cooling performance directly. It simply holds the heatsink in place. If your current pins are cracked, this pack provides twelve spares. It is a simple fix for older systems. Ensure your cooler is compatible with this push-pin style before buying.

Check before you buy

• Verify your motherboard uses the LGA 775 socket.
• Confirm your cooler uses push-pin mounting style.
• Check if your current pins are broken or lost.
• Ensure you have thermal paste for the CPU.
