Cast Aluminum Profile Corner Brackets and Fastener Kits, Silver and Black
Non-standard custom made. Ribbed cast-aluminum corner brackets and mounting kits for extrusion frames, enclosures and fixture joints. Bare brackets and kits are separate configurations. Price is per selected pack, not per photographed piece. Check the pack quantity and source reference before ordering.
Range and Selection
- Supplier references include2020,2028,2040,2430,3030,3060,3040,4040,4545,4080,4590,6060,8080and3038round-hole types. These numbers are interface references, not guaranteed finished dimensions.
- Regular, reinforced, flat-base/no-tab, long-slot, T-hole and round-hole configurations are not interchangeable. M6/M8 in selected bare-bracket names are fastener references, not a claim that the clearance holes are threaded.
- Body material is supplier-designated aluminum alloy, with ADC12 specified on some source images. Do not infer one alloy/finish specification for every option. Silver and black describe the selected appearance; confirm the exact coating, casting grade and certification if required.
- EU/CN identify supplier extrusion-slot hardware references, not conformity to a named standard. Match the real slot opening, internal cavity, fastener thread, bearing area and assembly clearance.
- Each kit contains one bracket and the fastening parts in its exact source-image component list. Multiply those per-set quantities by the number of sets in the selected pack. Bare bracket packs do not include bolts, washers or slot nuts. Extrusions are not included.

Installation and Custom Requirements
Check bracket seating, slot-nut fit, bolt diameter/length and washer bearing area before assembly. Some slider/T-slot nuts require insertion from the extrusion end before the frame is closed; side-insert or spring-retained nuts use different installation methods. Confirm the nut type in the chosen kit. Set tightening torque and load limits for the complete joint rather than relying on general supplier claims. These brackets are not rated lifting points.
Send the selected SKU and pack quantity, mating profile/slot drawing, load conditions, required bolt/nut interface, material, finish and tolerances for custom confirmation. No unsupported strength, corrosion-life, certification, factory ownership, promotional pricing or fixed dispatch promise is made. Contact boltte@boltte.com or BOLTTE on WhatsApp.
