Stainless Steel Hanger Bolts

Stainless Steel Hanger Bolts with two differenct thread type, one is machine thread, another is wood thread. produced by stainless steel 304, used for solar mounting system, work together with 3pcs of stainless steel flange nuts with serration and one pc of EPDM washer.

Stainless Steel Hanger Bolts Feature

A2-70 Stainless Hanger Bolts are free burrs, and free lamps, and no other defects affecting their serviceability.

To fasten the stainless steel flange nuts with serration with 15Nm down to the end of the thread. Position the seal against the low surface of the flange nuts.

Per batch of stainless hanger bolts, we do tensile testing, included the test data as mechanical properties, stress, tensile load, tensile strenth,fel yield force, rel yield strench, strenching length and extended gauge dis.

EPDM washers are made from non-recycled materials and are guaranteed for warranty more than 15 years.
