About MIL- SPEC Springs
These products are part of the United States Defense
Standard. They are used to help achieve
standardization objectives set by the U.S. Department
of Defense. They are known interchangeably as
“military standards”, "MIL-SPEC", “MIL-STD", or
"MilSpecs." These high precision designs meet
stringent technical requirements and are used in a
multitude of Military and Aerospace applications, both
defense and non-defense related. MIL-SPEC springs
are increasingly specified by other non-Defense
government organizations, technical organizations, and
highly regulated industries. The MIL-SPEC standard
for compression springs for loads below 20 lbs. is
AS24585; this standard was formerly MS24585. The
MIL-SPEC standard for extension springs for loads
below 30 lbs. is AS24586; this was formerly
MS24586.
• Cadmium Plated Music Wire in accordance with
SAE-AMS-QQ-P-416, Type II, Class 2.
• Zinc Plated Music Wire in accordance with
ASTM B633, Type II, Fe/Zn5.
• Corrosion Resistant Stainless Steel 302 per
ASTM A313 with passivation treatment in
accordance with ASTM A967. DFARS Compliant
material only.
About DFARS Compliance
DFARS regulates the supply country for certain
materials. It applies to Stainless Steel but does not
apply to Music Wire. For a complete explanation of
DFARS Compliance, go to the Regulatory
Compliance and Certification Page 342.
