Nickel-plated Hex Socket Cap Head Combination Screws
Brought to you by JINSIXI, Nickel-plated Hex Socket Cap Head Combination Screws combine a DIN 912 socket head screw with a set of captive (permanently attached) washers: one plain washer and one split spring washer. Since the washer is installed on the blank screw before rolling the threads, the washer remains in place and will not fall off the screw due to the diameter of the screw being larger than the initial diameter of the washer.

Product Details
Nickel-plated Hex Socket Cap Head Combination Screws can offer many benefits, especially in terms of quick and easy assembly options. A few of the most notable benefits are listed below：
Nickel-plated Hex Socket Cap Head Combination Screws are pre-assembled screws with washers that can rotate freely. Combination screws usually contain a flat washer and a split spring washer. Combination screws are produced by fixing the washers in place before rolling the threads on the screws. Since the diameter of the threads is larger than the inner diameter of the washers, the washers can only move in the unthreaded part and will not fall out. Combination screws improve design and manufacturing efficiency by combining multiple parts, fixed washers and screws into a multi-functional fastener.
