Product Description

High-Precision Custom Equipment Screws With Sandblasting And Electro-Polishing

Product Application:
Custom stainless steel screws for critical applications demand reliability, corrosion resistance, and precision.

Medical & Surgical Devices: Implant assembly screws, orthopedic adjustment screws, fasteners for diagnostic housings, and precision leadscrews in robotic surgical mechanisms.
High-End Industrial: Precision screws for optical mounts, semiconductor alignment, chemical valve actuators, and high-load food processing fasteners.
Aerospace & Defense: Critical fasteners for avionics, instrumentation, and ground support with high strength-to-weight ratio.
Laboratory & Analytical Instruments: Fine-pitch screws for focusing stages, sample positioning, and optical components.

Product Description:
Expert CNC milling of custom stainless screws for medical and industrial sectors. Engineered from premium stainless steel (303, 304, 316, 17-4PH) using multi-axis CNC lathes. Fully customizable: thread (metric, unified, Acme, ball), head (hex, flat, oval), drive (hex, Torx, slotted), geometries (shoulders, undercuts, tapered). Each screw ensures precision, finish, and material integrity for optimal performance in sterile or harsh environments.

	Material Certification	Mill certificates provided. Compliance with ASTM/ISO standards. Biocompatibility reports (ISO 10993) available for medical grades.
Manufacturing	Primary Process	CNC Turning & Multi-axis CNC Milling.
	Thread Production	Single-point CNC threading, thread milling, or rolling for superior accuracy and surface finish.
	Dimensional Tolerance	Standard Precision:±0.025 mm on critical diameters. High Precision:Up to ±0.005 mm achievable for critical features (e.g., lead screw pitch diameter).
Design & Customization	Thread Types	Full custom specification: Metric (ISO), Unified (UNC/UNF), Acme, Ball Screw profiles, Micro threads, Special pitches.
	Head Styles	Hex, Socket Head Cap, Flat, Oval, Fillister, Round, Custom profiles.
	Drive Types	Hex Socket (Allen), Torx (Including Security), Slotted, Phillips, Pozidriv, Tri-Wing, Spanner, Custom.
	Special Features	Shoulders, precision undercuts, knurling, drilled cross-holes, axial holes, special tip shapes (dog point, cone point).
Quality & Finishing	Surface Finish	As-machined, polished, electropolished (for medical), passivated, or coated (e.g., PTFE, PVD) upon request.
	Cleanliness	Cleaned and packaged per industry requirements (e.g., medical device cleanroom packaging).
	Inspection	100% dimensional inspection (CMM, optical comparator, thread gauging). Full material traceability.
Standards & Compliance	Quality System	Manufactured in an ISO 13485 (medical) or ISO 9001 (industrial) compliant environment.
	Relevant Standards	Can be manufactured to meet ASME/ANSI, DIN, ISO, or other international fastener standards as specified.
