Products + Tools

HEICO Group has a long history and in-depth experience of the science of bolted joints. Since the merger of its two production sites two years ago, the German manufacturer has continued to improve its operational and manufacturing efficiency, as well as become a catalyst for new product development. 

With its wide and diverse product portfolio of bolt locking devices and pre-tensioning solutions, HEICO is a leader in the field of fastening technology. In addition to the classic wedge lock washers, the company offers numerous user-friendly product combinations and innovative variations, including ring lock washers, wedge lock nuts and HLK washers for special steel constructions. 

HEICO-LOCK^®

The HEICO-LOCK^® combi-washers, honoured in December 2023 with a Best of Industry Award, are the most innovative of HEICO’s bolt locking devices. The functionality of the combi-washers, and all locking devices from the series, is based on the wedge locking principle. The proven wedge lock washers, with its radial ribs on the outside and opposing wedge surfaces on the inside, serve as the basis. When
pre-tensioning the bolted joints using HEICO-LOCK^®, the outer radial ribs are pressed into the counter part while the inner wedge surfaces effectively prevent the bolt from self-loosening. 

Small tabs on the inner plastic ring allows the pre-assembly of bolts and combi-washers, which simplifies the mounting process, making this solution especially suited to applications in difficult to reach areas. However, the most important advantage of the combi-washers is the high-level of flexibility for the user, as the bolt locking device can be used universally with any type or length of bolt.  

HEICO-TEC^®

With its HEICO-TEC^® tensioning systems, HEICO offers a fully comprehensive system to pre-tension extra large bolted joints quickly and easily without using expensive electric, pneumatic or hydraulic tools – only a commercial torque wrench is required. Tension nuts and bolts, in standard and in customised variants, also feature in HEICO’s product range, as well as an extensive selection of accessories including reaction nuts, protective caps and lubricants.
