Both chemical and mechanical fasteners are used to keep two or more objects together. Both are employed in masonry, concrete, construction, and other commercial applications. But which should you use for your project? Here, the team at Min Plastics & Supply, a top HDPE supplier in Honolulu, HI, has compared and contrasted the two options.

The Process

Chemical fasteners, also known as chemical anchors, use a special adhesive, which is injected into a hole drilled into the intended surface. The bolt is inserted after, and the product will set within 24 hours. On the other hand, a mechanical anchor is often drilled through the two adjoining parts to hold them together, semi-permanently or permanently. Non-permanent options include bolts, screws, and studs. A rivet, however, is a permanent fixture.

Benefits

One of the main advantages of mechanical anchors is that they can usually be removed if needed, which allows for re-work in the event of mistakes or changed plans. They are also cost-effective and readily available for professionals and amateurs alike.

Though more expensive, the permanent bonds of chemical anchors are strong and durable. With their elasticity, they can fully fill any hole, leaving no gaps for water or other unwanted substances to seep in. 

Uses

Construction sites, particularly home building, commonly use mechanical fasteners. Structural work for walls, floors, ceilings, and foundations relies on nails and screws. These components are also used in woodworking and jewelry-making.

Chemical fasteners are more often used with brittle materials. A nail in concrete, cement, or brick can damage the surface, whereas a chemical resin will provide gentle yet stable anchoring. Using chemical fastening all over results in a much more lightweight structure as well, which is an advantage for aircrafts.
