Sometimes the regular imperial measurements for hardware fasteners simply won’t work with the products you may have purchased and imported from overseas. Many other countries instead use metric measurements. The Coating House offers metric screws, metric washers, metric bolts and metric nuts wholesale so you can obtain the right fasteners for the project that will be the perfect fit.

Shoulder Screws are available in heat treated alloy steel and all grades of stainless. Featuring an enlarged, unthreaded cylindrical shoulder, socket shoulder screws are used in applications where parts are required to rotate or slide.

Military and aerospace contractors who create machinery and equipment have no margin for error. They rely on parts and hardware that have been tested to meet military standards — referred to as “mil-spec” hardware because it meets military specifications. The Coating House includes manufacturer’s certification with all of our mil-spec products so you can have full traceability and confidence that you are getting the correct part. Mil-spec fasteners are commonly used in the defense, government, marine, nuclear, and shipbuilding industries.

Machine screws without a head exert pressure against an abject to hold it in place. Available in a variety of materials from stainless to alloy with plated or black ox finish.

Captive Screws are a specialist fastener that is retained within a target assembly or housing, typically with an unthreaded portion below the head, called a reduced shank. The screw is captive meaning it cannot be totally removed from the hole or fall out when items are disassembled.

The Coating House offers a huge variety of industrial hardware. Let our in-house Certified Fastener Specialist help you choose the correct hardware for any application.
