Pre-drilling: Pre-drilling pilot holes is crucial in preventing splitting, particularly in materials like plywood or particle board, which are susceptible to damage when fasteners are driven directly into them. By drilling a hole slightly smaller than the outer diameter of the insert nut, you create a guide for the insert nut to follow during installation, reducing the likelihood of splitting.

Countersinking: Thin materials require special attention to ensure that the insert nut sits flush with the surface. Countersinking involves creating a recess around the hole where the insert nut will be placed. This prevents the nut from protruding above the surface, which not only improves the aesthetic appearance but also reduces the risk of snagging or catching on surrounding objects.

Material Selection: The choice of insert nut is crucial, as different materials have varying levels of compatibility with specific materials. For instance, in softer materials like MDF or pine, using insert nuts with a wider flange distributes the load over a larger area, minimizing the risk of splitting. Additionally, consider the material composition of the insert nut itself; for example, brass insert nuts are often preferred for their ability to provide a strong hold without damaging delicate materials.

Insertion Technique: When inserting the insert nut into the pre-drilled hole, it's important to do so carefully and with precision. Inserting it straight and without excessive force reduces the likelihood of causing damage to the surrounding material. Utilizing a tapping motion or a threaded insertion tool can facilitate smooth insertion and minimize the risk of splitting.

Appropriate Torque: Over-tightening the screw or bolt into the insert nut can exert excessive pressure on the surrounding material, leading to splitting or damage. It's crucial to adhere to the manufacturer's recommended torque values to ensure a secure hold without compromising the integrity of the material.

Adhesive Use: Applying a small amount of adhesive, such as epoxy or wood glue, around the perimeter of the insert nut before insertion can provide additional reinforcement to the material. This adhesive acts as a secondary bonding agent, strengthening the connection between the insert nut and the material and reducing the risk of splitting, particularly in high-stress applications.

Test Fit: Before finalizing the installation of the insert nut, performing a test fit is essential to ensure proper alignment and fit. This allows for any necessary adjustments to be made before permanent installation, reducing the likelihood of errors and ensuring a secure and reliable fastening solution.
