Screws are essential fasteners in MRO and automation industries, known for their versatility in joining materials securely. Common types include machine screws (threaded for nuts), self-tapping screws (creating their own threads), and wood screws (coarse threads for wooden surfaces). High-strength options like socket head cap screws withstand heavy loads, while specialized variants such as shoulder screws serve as pivots in machinery. Materials range from stainless steel (corrosion-resistant) to alloy steel (durability). Screws feature diverse drive types (Phillips, slotted, hex) and head styles (pan, flat, round) to suit specific applications. Thread-locking screws prevent loosening in vibrating environments, making them ideal for automated equipment maintenance.
