Customer Questions & Answers
-
Question:
What is the E-Z LOK 400-4 threaded insert made of?
Answer: The E-Z LOK 400-4 threaded insert is constructed from high-quality brass, which promotes durability and resistance to corrosion. Brass is a widely preferred material in applications subject to wear and tear due to its strength and longevity. This makes it an ideal choice for both permanent and temporary fastening solutions in wood and composite materials. -
Question:
What types of projects can I use the E-Z LOK 400-4 inserts for?
Answer: E-Z LOK 400-4 inserts are versatile and can be used in a variety of projects, including cabinetry, furniture assembly, and DIY crafts. They are particularly beneficial for applications where repeated assembly and disassembly are required, as they maintain thread integrity without stripping. Ideal scenarios include attaching hardware in cabinets or securing components in the assembly of wooden furniture. -
Question:
How do I install the E-Z LOK 400-4 threaded inserts?
Answer: Installation of the E-Z LOK 400-4 threaded inserts involves drilling a properly sized hole in your material, applying adhesive if preferred, and then driving in the insert with the right installation tool. The knife thread design allows for easy insertion and provides a strong hold in various materials, ensuring that it remains securely in place. This method is especially helpful in applications requiring a solid retention without the risk of damage to the surrounding material. -
Question:
What is the significance of the 14-20 internal threads?
Answer: The '14-20' designation refers to the internal thread diameter and pitch of the insert, indicating that it is designed for #14 screws with a thread pitch of 20 threads per inch. This specification is critical for compatibility with certain screws, ensuring strong fastening without any slippage. These inserts work excellently for tasks requiring a solid attachment in furniture and tools that utilize these specific threads. -
Question:
Can the E-Z LOK 400-4 threaded inserts be used in hard materials?
Answer: Yes, E-Z LOK 400-4 threaded inserts are engineered to be effective even in hard materials such as hardwoods and various composites. Their knife thread technology enables them to grip tightly without damaging the material during installation. A common application would be reinforcing threaded holes in solid wood furniture, providing a lasting and reliable fastening mechanism. -
Question:
What is the benefit of using knife thread inserts like the E-Z LOK 400-4?
Answer: Knife thread inserts like the E-Z LOK 400-4 feature a unique cutting edge that enables them to slice through the material during installation. This allows for greater retention as they create a tighter fit and reduce the risk of the insert pulling out over time. These inserts are particularly useful in situations where vibration could compromise the fastening, such as in machinery or vehicles. -
Question:
Can I use these inserts in both soft and hard woods?
Answer: Absolutely! The E-Z LOK 400-4 threaded inserts are designed for use in both soft and hard woods. Their knife thread design allows them to secure fasteners effectively in softer materials without causing blowouts, while still holding strong in harder woods. This adaptability makes them suitable for a range of woodworking projects, from casual DIYs to professional cabinetry. -
Question:
How many inserts come in a pack of E-Z LOK 400-4?
Answer: A pack of E-Z LOK 400-4 includes 25 threaded inserts. This quantity provides sufficient supplies for multiple projects, enabling both small repairs and larger furniture assembly tasks. Additionally, having surplus inserts on hand can be convenient for ongoing or unforeseen projects, ensuring you never run out in critical situations. -
