These custom slotted T-bolts were manufactured in 316 stainless steel with plain finish based on drawings we created using provided samples. Unlike the typical slotted drive application we see these t-bolts incorporated the slot for marking/indication purposes to signal the position of the head from the back side. Each bolt was wrapped in protective netting to avoid damage to the head and thread during transport.
