Our Most Popular Concrete Construction Parts

Tengco supplies custom concrete construction accessories for precast, formwork, and concrete forming applications. We work with established manufacturing partners to provide dependable components designed around customer specifications, performance requirements, and production needs.

Our team can work from drawings, sketches, samples, or existing parts to develop custom concrete accessories for demanding applications. Components can be manufactured for high-load requirements, ease of assembly, durability, and efficient installation on the jobsite.

Some of our most popular concrete construction products include:

Coil Bolts

Tengco coil bolts are designed for concrete forming and precast applications where fast, reliable fastening is important. Their coarse coil thread helps shed debris during use, which can improve thread engagement and reduce buildup in demanding construction environments.

Coil bolts are available in multiple sizes and configurations for custom concrete formwork, forming, and precast applications. Their reusable design allows for repeated tightening and removal while maintaining secure engagement.

Penta Bolts

Penta bolts use a five-sided head that requires a matching Penta socket for installation and removal. This provides an added level of tamper resistance for applications where unauthorized access or vandalism is a concern.

Learn more about how Penta bolts improve security or view Tengco's Penta bolt products . Common applications include polymer concrete vaults, meter boxes, pole-top transformers, and other secured access points.

Screed Pads

Tengco screed pads are designed to help establish consistent concrete elevation and leveling during placement. They can be used in a variety of concrete construction applications where accurate depth and level are important.

Our standard screed pads feature a 1/2" NC threaded stud centered in a 3" diameter base. Custom sizes and configurations can also be developed based on project requirements.
