100PCS 1/4-20 Embedded Concrete Expansion Anchor 3/8 Bit Stainless Steel 304 Drop in Anchors for Solid Concrete

Description If you are a construction worker, or work in the mechanical, construction, transportation, and other industries, and need to control the expansion rate and expansion range of concrete, then our expansion anchor will be one of your essential choices. Because of its excellent material, portable and lightweight structure, and excellent performance, it can become your good assistant in the work.DetailsDiamond Pattern: This design makes it look not only more beautiful but also helps to increase friction and play a non-slip role and help to grip and hold the insert in the concrete well.Smooth Surface: The surface of the product is simply brightened and deburred to make it more comfortable to touch and look more lustrous.ApplicationIt is suitable for new energy, light industry, petrochemical industry, communication industry, marine industry, machining, medical machinery, construction industry, automotive manufacturing and bridge construction, and suitable for holes with a diameter of 0.307-0.315inch.SpecificationsMaterial: 304 Stainless SteelSurface Treatment: Brighten and DeburredMounting Type: Drop-inNumber of Pieces: 100Thread Size: 1/4-20''Notes1. These anchors should only be used in masonry and solid concrete, please do not use them for block or brick-based materials.2.

• Sturdy and Durable: It is made of high-quality 304 stainless steel that is very sturdy, wear-resistant, rust-proof, and impact-resistant, which can effectively protect the internal parts and prolong the service life.
• Safe and Reliable: It does not loosen easily and its reliable expansion control mechanism has undergone rigorous safety testing to ensure safe use.
• Good Performance: This product features a heavy-duty anchoring system and internal thread, typically used in conjunction with machine screws, bolts, and screws to secure the fixing device to concrete and other masonry materials. Due to its design, it is also commonly used for temporary structures. It can effectively reduce the shrinkage stress and deformation of concrete while reducing energy consumption and improving engineering efficiency.
• Cost Saving: Since expansion anchors are made of precast concrete elements, while the anchor itself is always in the concrete, the bolts you use to hold it in place can be removed and reused. Thus, it helps you save money.
• Drop-in Design: Our anchors feature a drop-in design that allows for precise control of expansion rate and expansion range to suit different concrete elements and engineering requirements.
