Since 1901, McMaster-Carr has been the standard industrial reference book of the Western Hemisphere. The 3,500 page catalog is sent only to established customers with very limited distribution- making it a coveted and respected resource. We’ve been big fans ever since we first laid eyes on that iconic yellow cover in the late 90’s. We combed through the 500,000+ products available to highlight some of our favorites. Masterlist offers a curated list of timeless pieces, available directly from McMaster-Carr.
