摘要： A swivel hanger system includes an anchor member with an anchor head disposed at an end of the anchor member and an elongated body, where at least a portion of the elongated body is configured to be inserted into a support member when the system is connected with the support member. The system also includes a swivel member with an open end extending to a hollow interior of the swivel member, where the open end is configured to rotatably couple with the anchor head such that the anchor head is located within the hollow interior and the elongated body extends through the swivel member open end. The system further includes a stop structure to limit an insertion distance at which the anchor member is inserted into the support member.

摘要： A self-tapping screw head structure includes a screw head, a rod, a cone and a thread. A direction of the thread surrounding the cone and the rod determines a tapping direction. The screw head includes a top portion, a first neck portion connected to the top portion and having a circumference decreasing towards away from the top portion, a plurality of recesses recessed at a surface of the first neck portion, and a second neck portion connected to the first neck portion and having a circumference gradually decreasing towards away from the first neck portion. Each of the plurality of recesses includes a cutting end, a crumb guiding end away from the cutting end, a first accommodating groove and a second accommodating groove. A recess depth of the first accommodating groove is greater than that of the second accommodating groove.

摘要： Disclosed is a chip removal structure of a screw. The screw includes a screw head. A shank extends downward from the screw head. The shank has an outer circumferential surface on which a thread is formed in a surrounding form. The shank has a lower end that is formed with a tapering tail section. The thread is extended to the tapering tail section. The tapering tail section is formed, through cutting or pressing, with two or more chip removal grooves. The spacing distance of the chip removal grooves can be adjusted as desired. The chip removal grooves are set at an inclination angle and any one of the chip removal grooves may exceed or may not exceed a screw center line. The chip removal grooves on the left side are each 0.5 to 4.5 times in width of the chip removal grooves on the right side.

摘要： A composite screw includes a tapping end portion that includes a circular bottom surface, a peripheral surface and a main thread. The peripheral surface extends from the circular bottom surface. The main thread is formed around the peripheral surface. A reception recess is recessed from the circular bottom surface and the peripheral surface. The main thread has a discontinuation where the reception recess opens at the peripheral surface. A rigid body and a weld material fill the reception recess. The rigid body has an outer surface and an auxiliary thread. The outer surface is exposed from the reception recess. The auxiliary thread is formed on the outer surface and connected to the main thread to fill the discontinuation.
