Now exceeds 30 years of specialization in stainless steel fasteners and wire, with experience and expertise second to none in the fasteners industry. Our company is about talents. We have some of the best talents in the industry and make talented products of unique features. We specialize in making innovative threading dies. Instead of the conventional round thread, we have introduced the square and triple threads extensively in wood, self-drilling and concrete screws. It is about substantial drive-in torque reductions and better gripping and holding power, thereby improving the level of product safety. We announce with pride we now make the best wood, decking, concrete, self- drilling and self-locking screws in ferrous and non-ferrous steels have been used extensively for collation and on some of the hardest woods without breaking. The self-drilling screws in the square threads are best suited for heavy-gage metals showing astonishing drilling capacity as described in the latter pages. The self-locking screws in various special thread forms that sell at a fraction of the nylon patch screws are used in the auto, computer and the toy... industries. We continue to discover more and more useful applications of the square and triple threads in an ever-expanding scope
