In construction infrastructure, mechanical and electrical installation, steel structure matching, and overseas foreign trade projects, nails, car repair geckos, internal pressure geckos, tooth strips, bolts, nuts, spring washers, and flat washers are widely used basic fastening kits, and product selection directly affects engineering safety and service life.
Nails: commonly used for wooden structures, light steel keel, simple fixation, with a wide range of specifications and categories. Galvanized treatment can enhance rust prevention ability, and are widely used in home decoration and factory construction.
Car repair gecko (wedge-shaped mechanical anchor bolt): relying on mechanical locking to bite the concrete substrate, it is resistant to vibration, has strong bearing capacity, and is immediately stressed after installation without waiting for curing. It is widely used in heavy-duty conditions such as seismic supports and hangers, curtain walls, equipment bases, and steel structure supports, and is the preferred anchoring product for engineering projects.
Internal expansion anchor bolt: It belongs to the type of built-in expansion, which is inserted after drilling and screwed into the screw to achieve internal expansion and fixation. It is suitable for fixing ceilings, air ducts, fire-fighting equipment, and lightweight equipment, and is suitable for blind hole installation scenarios. The construction is convenient and efficient.
Tooth strip (fully threaded screw): threaded and fully threaded, can be cut to length as needed, used with nuts and washers, for ceiling hangers, bridge frames, steel structure connections, chemical equipment assembly, and supports customized non-standard lengths.
Bolt&Nut: Fastener core connection pair, with multiple strength options of 4.8, 8.8, and 10.9 levels, complete in carbon steel and stainless steel materials. It is a basic connection for equipment assembly, steel structures, and pipeline flanges. Thread accuracy determines assembly smoothness and preload stability.
Flat pad: increases contact area, disperses tightening pressure, protects the surface of the workpiece, prevents nuts and bolts from damaging the substrate, and is a standard accessory for bolt and nut assembly. Both standard parts and non-standard shapes can be produced.
Elastic pad (spring washer): relying on the elastic force of the spring to achieve anti loosening and offset the risk of loosening caused by vibration, it is often used together with a flat pad and is mostly used in assembly scenarios with vibration conditions.
Procurement reminder: For outdoor humid environments, galvanizing and hot-dip galvanizing are preferred; 304/316 stainless steel is selected for corrosion conditions; Priority should be given to verifying the strength level and tensile testing report for heavy-duty vibration projects.
