Cold Heading & Thread Rolling

We are the only company in our specialty of clamping and coupling devices to manufacture its own T-bolt, eyebolt, pins and specialty fasteners to stringent aerospace and industrial standards. For nearly 30 years, Voss has produced fasteners from alloy steels, stainless, A286 alloy, and nickel alloy 718 for our full line of products.

In-house metallurgy and testing laboratories are utilized to monitor each heat of wire through all production steps to the finished fastener. This expertise is now available to the aerospace industry for production of a variety of fasteners.Voss Aerospace also manufactures high shear strength rivets of A286 stainless steel and nickel alloy 718.

Capabilities

Materials:

A286 CRES; 1038 and 4037 alloy steels; 305, 316, 431 stainless steels

Threads:

#10-32 UNF and UNJF; 1/4-20 UNC; 1/4-28 UNF and UNJF; 5/16-18 UNC; 5/16-24 UNF and UNJF; 3/8-16 UNC; 3/8-24 UNF and UNJF; 1/2-13 UNC; MJ4, MJ5 and MJ6 (metric). Other thread sizes are available upon request.

All threads are rolled (after heat treating, if applicable) to provide stronger, more exact and uniform threaded fasteners.

0.190 inch diameter to 0.500 inch diameter, 5 inches long.

Testing:

Fatigue and stress rupture (elevated temperature) provided to certify part quality. Hardness, tensile, and metallography services available as required.

Special Fasteners:

Facilities are also used to supply specialty type fasteners (unique configuration, material, small to medium lot size, etc.) for aerospace, general industrial and OEM use, such as automotive or marine applications.
