Stainless Steel U Type Spring Cage Clip Nut
The Stainless Steel U Type Spring Cage Clip Nut is a pre-installed captive threaded fastener engineered for long-term anti-rust assembly in humid, corrosive and outdoor environments. It consists of a stamped elastic U-shaped stainless steel spring clip and an integrated cylindrical threaded insert, which can be slid and locked into rectangular rack slots to avoid falling or shifting during bolt installation and equipment maintenance.
Fabricated entirely from premium 304 stainless steel, this clip nut delivers outstanding elastic recovery performance, tensile strength and permanent rust-proof capacity. The surface undergoes polishing and passivation processing to form a dense inert protective film, effectively resisting moisture, salt fog, acid mist and ultraviolet corrosion, maintaining stable mechanical performance under coastal, medical, food and other corrosive working conditions where carbon steel fasteners will quickly oxidize and fail.
The bent U-shaped spring arms provide consistent elastic clamping tension after being inserted into metal frame slots, firmly gripping the plate wall to prevent sliding or dropping during tightening operations. The integrated cylindrical threaded insert features precisely tapped internal threads matching standard metric bolts; small positioning holes on the base plate support spot welding for extra fixation if required. The clip allows minor floating adjustment to align misaligned bolt holes, drastically cutting assembly time on automated production lines.
Stainless steel U type spring cage clip nuts are widely applied to outdoor stainless steel equipment cabinets, marine electrical control housings, medical precision instrument chassis, food processing machinery frames, stainless steel network racks and all sheet metal assembly projects exposed to damp or mildly corrosive atmosphere. Its all-stainless-steel construction eliminates later rust replacement costs and ensures long service life for special environment equipment.
We provide full OEM and ODM custom manufacturing services and support tailor-made production based on customer technical drawings, physical samples and special dimensional demands. Custom thread sizes, clip width & length, spring plate thickness and dedicated export packaging can be customized to satisfy marine, medical and food machinery engineering project requirements. Private laser marking and custom brand printing services are also offered for stainless steel hardware distributors, medical equipment manufacturers, marine engineering contractors and food machinery suppliers.
Each Stainless Steel U Type Spring Cage Clip Nut is produced under strict stainless steel fastener quality control standards. All finished clip nuts pass comprehensive dimensional inspection, thread precision test, spring elasticity fatigue sampling test and surface anti-corrosion passivation performance verification before shipment, to guarantee accurate thread tolerance, stable lasting clamping force and uniform long-term rust-proof performance for every production batch.
