JCP Metalfix Loose Washer

The integrity of a building’s envelope often relies on the smallest components. The JCP Metalfix Tekscrew Washer is a critical element in ensuring long-term structural health and weatherproofing in metal-to-metal and metal-to-timber applications. When installing cladding or roofing, the point of entry for any fastener is a potential weak spot for leaks and rust. This washer is specifically engineered to mitigate those risks by providing a permanent, flexible seal that conforms to the profile of the material being fastened.

Constructed to handle the high torque associated with self-drilling Tek screws, the Metalfix washer features a robust design that resists over-squashing. In many standard washers, excessive pressure can cause the sealing element to splay or crack, leading to premature failure. JCP has designed these washers to maintain their structural integrity, ensuring that the seal remains tight even under significant mechanical stress. The metallic backing provides the necessary rigidity to distribute the clamping force of the screw across a wider surface area, which is vital when working with thin-gauge steel or aluminum where pull-through is a concern.

Beyond waterproofing, these washers play a significant role in preventing galvanic corrosion. By acting as a buffer between the fastener and the sheeting, they reduce the contact between dissimilar metals, which is a primary cause of degradation in industrial environments. The resilient material also offers excellent UV resistance, meaning the seal will not become brittle or perish when exposed to direct sunlight over many years. For contractors and installers, using JCP Metalfix Tekscrew Washers means fewer call-backs for leaks and a professional finish that stands up to the elements. They are the industry-standard choice for ensuring that every screw hole is as secure and dry as the day it was drilled.
