Drilled Bolts

Using drilled bolts along with a safety wire is an excellent fastener securing method that is easy to inspect. We machine these in-house and keep many sizes in-stock in both Hex Head and Socket Head. We can also custom drill safety holes to your specifications in a variety of materials and finishes.

We are committed to the quality of our products and services because we value the relationships we have with our customers. We strive to meet or exceed our customers’ requirements and expectations. To that end, we have established an ISO 9001:2015 certified quality management system.

Nord-Lock® Washers

A system comprised of a pair of washers that has cams on one side and radial teeth on the other. Since the cam angle is greater than the thread pitch, a wedge effect is created, preventing the bolt from rotating loose.

Some key benefits: reusable, maintains high clamp load, quick and easy installation, high corrosion resistance, reliable and verifiable locking function. Proven in Junker vibration test and NASM impact and vibration test.

Inventory Management

We understand that some of our customers may have a need for immediately available parts but are usually constrained by the costs associated with maintaining the required inventory. At Northwest Fastener, we work side-by-side with our customers to help them with their inventory demands. This is why we offer supply chain improvement solutions to qualified customers.
