Product Details
This Custom Stainless Steel Screw is engineered for assemblies requiring high strength, clean surface quality, and consistent dimensional accuracy. Manufactured from CRES 17-4PH per AMS 5643, Condition H900, the part provides excellent mechanical performance, corrosion resistance, and long-term stability-making it suitable for aerospace hardware, industrial equipment, and precision instruments.
Precision Dimensions
Each screw is produced to strict inch-based tolerances to ensure repeatable fitment in high-accuracy applications:
Thread Size: 0.250-28 UNF-3A
Small Through Hole: Ø0.053 – 0.033 in
Overall Length: 1.1 in
Head Width: 0.28 in
Runout Requirement: Diameters sharing a common axis must remain within 0.010 in
Radius Requirements: Machined fillet radii 0.005 – 0.020 in
Deburr & Edge Break: 0.003 – 0.015 in
These tight and controlled features make the component comparable to a Precision Machined Fastener, ideal for assemblies where positional accuracy and clean geometry are essential.
High-Performance 17-4PH Stainless Steel
The screw is produced from 17-4PH precipitation-hardened stainless steel, offering:
Exceptional tensile and yield strength in H900 condition
Strong resistance to wear and fatigue
Stable performance under vibration and load
Excellent corrosion resistance
Its strength-to-weight ratio makes it a reliable High-Strength Threaded Component for both structural and functional applications.
Surface Finish & Protection
To ensure long-term durability and reliable performance in harsh environments, the screw is finished with:
Passivation per ASTM A967
Passivation removes free iron from the surface, enhances corrosion resistance, and provides a clean, uniform finish suitable for exposed or high-precision assemblies.
Applications
This Custom Stainless Stainless Steel Screw is designed for:
Aerospace mounting and bracket systems
Precision instrumentation and measuring devices
Industrial automation equipment
High-performance machinery and mechanical assemblies
Custom fastening points in engineered designs
Key Features
Tight UNF-3A thread tolerances
Cleanly machined geometry with controlled radii
