Spacers or standoffs as they’re more commonly known are small devices that serve a very big function in reducing friction, abrasion and also providing the correct fit and grip to different moving parts. Some spacers are also used for insulation purposes where they can prevent metal parts from touching each other and creating an electrical fault or hazard. They may be used to fasten and separate cables and in different circuitry applications.
Different materials may be used to manufacture spacers. Generally for hard-wearing applications, metal spacers may be recommended, while plastic and PVC spacers are used for their non-conducting, non-corrosive properties. Metals used include aluminum, brass, nickel, stainless steel and some metal alloys for decorative purposes. Spacers may be round or hexagonal, with inner threads to ensure tightening and a good fit and grip.
Brass standoffs are used extensively in decoration and interior design or furniture applications. They can be used to separate glass from its mountings in shelves and display cabinets. Glass panels, screens, illuminated signs, photo frames, etc are places where brass standoffs can be used, with a variety of finishes like chrome or nickel plating or polished silver for great finish.
Stainless steel spacers are mostly for both outdoor and indoor applications like mirror and sign mounting. They are fitted with soft vinyl washers to ensure better grip and also prevent scratches and abrasion.
Aluminum spacers can be used in outdoor applications since they do not rust, corrode or get damaged by weathering. When they are smooth machined, finished by anodizing and made of best quality aluminum, they provide a good decorative finish for photo mounting, art displays and architectural murals and other decorative panel works.
Security spacers: These spacers have additional security and tamper proof facilities. The front caps can be screwed on securely and lock the panel or illuminated pane in place and retain it safely in position. These spacers are used to mount valuable art works, photos and documents in museums and other archival facilities. They can also be used to hold glass panels, photo frames and signs in place while providing good decorative elements.
Design elements for spacers include the push-in type with winged tips to ensure locking, reverse locking types for circuit boards, wide-based spacers for use in heavy PCB-applications, metric spacers which provide insulation and reduce vibration, snap-ons for use in PCBs and standard spacers for use in plumbing applications.
Depending on your specific requirements you can purchase spacers from your local hardware store or order them online from the manufacturers who may offer free samples and shipping if you’re making a bulk purchase.
