41x41 Unistrut Slide Nut (4 mm Hole)

A standard slide nut (or channel nut) designed for a 41 mm × 41 mm Unistrut channel features specific outer geometry to lock inside the channel lips, while your custom requirement specifies a central 4 mm clearance hole. Below are the geometric specifications, a 2D CAD engineering layout, and the parameter tables required to model this part in software like AutoCAD or SolidWorks. Standard 41x41 Channel Profile Context The slide nut is designed to slide inside a channel that is 41 mm wide and 41 mm deep. The internal groove profile dictates the nut's outer geometry: • Channel Outer Width: 41 mm • Channel Inner Opening (Lip Gap): 22 mm • Nut Width (W): 36 mm (to allow insertion and a 90° turn inside the channel) • Nut Length (L): 19 mm 2D CAD Drawing & Dimensions TOP VIEW (X-Y Plane) <------------ W = 36 mm ------------> +-------------------------------------+ ^ | |// //| | | ================================= | | | |// //| | | |// ( O ) //| | L = 19.0 mm | |// <-d-> //| | | | ================================= | | | |// //| | +-------------------------------------+ v SIDE VIEW (X-Z Plane) <------------ W = 36 mm ------------> +----+ +----+ ^ hg = 1.5 mm | +-----------------------------+ | v | | ^ | [ | ] | H = 6.0 mm +---------------------------------------+ v Dimension Parameter Table All measurements are in millimeters (mm). Feature Parameter Symbol Dimension Value Notes / Description Nut Width W 36 mm Fits across the internal 41 mm channel width. Nut Length L 19.0 mm Allows the nut to turn 90° inside the channel lips. Total Height H 6.0 mm / 8.0 mm 6 mm is standard for light loads Groove Depth hg 1.5 mm Serrated teeth rows that bite into the turned-in channel lips. Hole Diameter d ∅ 4.0 mm Your Spec: 4.0 mm for clearance. Hole Position \(X_c, Y_c\) Center aligned X = 18 mm, Y = 9.5 mm from bottom-left corner. Modeling & Manufacturing Tips 1. Serrated Teeth: The cross-hatched areas marked with // in the top view represent a series of teeth. These lock against the intake lips of the Unistrut strut. 2. Chamfered Corners: The top-right and bottom-left corners are heavily chamfered/rounded (R ≈ 9.5 mm) to allow clockwise rotation into the channel, while the opposing corners remain square to stop rotation past 90°.
