A shear stud bolt is essentially a steel rod with a head on one end and a threaded end for anchorage. They are typically used in composite beams and floors where they act as connectors between the steel beam and the concrete slab. The term shear refers to the force that tends to slide one part of a structure over another, perpendicular to the direction of the force. In such scenarios, shear studs serve as a critical line of defense against these potentially damaging forces.

Chemical anchor bolts are specialized fasteners that utilize a two-part adhesive system to bond with the concrete substrate. Unlike traditional mechanical anchors that rely purely on physical expansion or friction to secure themselves within the concrete, chemical anchors use a resin or adhesive, which is mixed with a hardener, to create a strong bond. This resin is typically injected into pre-drilled holes in the concrete before the anchor bolt is inserted. As the resin cures, it forms a very strong adhesive bond with both the bolt and the concrete, leading to excellent load-bearing capabilities.

EPDM, a synthetic rubber, is known for its excellent resistance to heat, ozone, and numerous chemicals, making it an ideal material for manufacturing washers used in fastening systems. The addition of a washer to a fastener significantly enhances its functionality by distributing the load evenly, preventing damage to the mating surfaces, and ensuring a tight seal. The EPDM washer, with its resilient nature, adds an extra layer of protection against leaks and environmental ingress.
