Custom Stainless Steel CNC Machined Hexagon Socket Screw with High Corrosion Resistance and Grooved Fastener Design

Situo Hardware specializes in custom manufacturing of stainless steel hexagon socket grooved screws, head-slotted inner hex bolts, 304 grooved hex socket fasteners, and CNC non-standard slotted machine screws. Our hardware supports industrial automation tooling, inspection jigs, precision molds, intelligent modules, and mechanical equipment assembly.

These stainless steel hexagon socket grooved screws are integrally CNC precision turned from 304 or 316 stainless steel bar stock. The head features a standard hexagon socket for wrench driving with additional positioning or limiting grooves. They can be tightened and disassembled using a hex wrench, while the grooves provide functions such as limit, anti-rotation, circlip fixing, and position sensing.

Available in industrial-grade 304 and 316 stainless steel. 304 offers good general rust resistance, while 316 provides superior acid and salt-spray resistance for humid, outdoor, and mildly corrosive conditions.

Integral CNC turning completes both inner hex hole and grooves in one process, maintaining tight tolerances for groove width, depth, and position with smooth burr-free groove walls.

Combines hexagon socket drive and head grooves. Hex wrench handles high-torque operations while grooves serve for position-locking and anti-rotation, simplifying mechanical component design.

Various groove types available: annular groove, straight slot, single-side slot, double-side slot. Customizable groove depth, width, location, screw diameter, total length, thread length, and special head shapes.

Vibratory finishing, passivation, and polishing for stainless steel. Passivation improves salt-spray resistance; polishing delivers smooth appearance for exposed positions. All sharp edges are deburred for smooth installation.

Comprehensive inspection process including incoming raw material inspection, in-process dimension sampling, full inspection for critical groove sizes, thread go/no-go test, and burr trimming.

• Grooved limit & anti-rotation fasteners for tooling fixtures and inspection jigs
• Circlip-fitting positioning hex socket screws for precision molds and automation modules
• Position-locking connecting fasteners for instruments and intelligent machinery
• Slotted bolts for limit and stop function on rotating shafts and adjustment assemblies
• Corrosion-resistant grooved stainless steel fasteners for humid and outdoor equipment
• Non-standard assemblies requiring both clamping force and groove-based position locking

Advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines). Maximum processing outer diameter: 60mm. Minimum control tolerance: 0.001mm.
