Bolt and lock

Start by matching the thread size, length, and head type to your application. A common set includes M6x70 mm bolts with hex heads measuring about 11.3x4 mm, flat washers around 11.8x1.4 mm, and a matching lock washer set to prevent loosening. These dimensions fit many home appliances, furniture assemblies, and DIY projects, offering a practical balance of strength and ease of installation. The assortment typically uses 304 stainless steel for durability and corrosion resistance.

Hex bolts provide the main fastening force, while flat washers distribute pressure to protect surfaces. Lock washers add resistance to loosening under vibration, which is particularly important for moving parts or frequent use. In a six-piece set, you’ll find all these components together, designed to work as a cohesive hardware kit for home repairs, furniture assembly, and appliance mounting.

Yes. Some entries describe high-security options like electric drop bolt locks with fail-secure operation, aluminum alloy bodies, and stainless steel bolts. They are tested for hundreds of thousands of cycles and operate on a low-voltage DC supply. These products are ideal for wooden, metal, or glass doors and can provide robust protection for controlled-access areas while integrating with existing door hardware.

Many items are designed for straightforward installation and compatibility with common door materials. For bathrooms or interior spaces, copper bolts and door bolts are noted for simple mounting. When integrating high-security locks, ensure the mounting surface supports the bolt strike and that the door’s frame can bear the force. A clean, level installation helps maintain reliable alignment and smooth operation.

Choose corrosion-resistant materials like stainless steel or brass for durability in humid spaces. Verify that the lock’s bolt and strike are sized to fit your door thickness and material, and consider the door’s construction (wood, metal, or glass). For high-traffic or exterior doors, prioritize locks tested for many cycles and with secure operating mechanisms to reduce the risk of wear or jamming over time.

Yes. Nut-bolt-sets and compatible fasteners allow you to assemble fixtures across multiple locations. When mixing pieces, ensure thread compatibility and matching material grades to avoid galvanic corrosion. This approach lets you outfit several doors or appliances with consistent hardware performance while keeping installation efficient and standardized.
