Hardware for Flying/Rigging the SP-4:
Eyebolts or bracket bolts should be M8 metric thread. Eyebolts and bracket bolts must conform to certain minimum strength criteria for safety reasons. Unspecified eyebolts found at local hardware stores are not strong enough to maintain safety for overhead flying or rigging. Use only forged steel shoulder machinery eyebolts designed for rigging use, which adhere to the stated standards as outlined b e l ow.

Hardware Specifications:
Forged shoulder machinery eyebolts should be an M8 size, 1.25 mm per thread, and must conform to DIN 580 or ASTM A489, for Germany, BGV-C1 is the relevant standard. Minimum shank length should be 26 mm. The eyebolts should be rated for a minimum of 1,000 lbs straight pull working load.Bolts used on custom mounting brackets must be certified to be a metric grade 8.8 or better.If there are any questions regarding the proper hardware or practices for safe flying or rigging of the Peavey SP® 4, contact a certified structural engineer, or consult with those local rigging companies who have trained and certified personnel.
