Pt#, Series 50. Press-In - No flange Brass Insert, 50PK

4-40x .140 Brass, Press-In - No flange Insert, Series 50

• •Press-In Inserts are ideal for use in softer plastics to provide a reusable thread which can meet the tightening torque requirements for a threaded joint.
• •These Inserts are designed to reduce installation cost at a sacrifice of torque and pull-out performance.
• •Helical knurls are used to provide both torque and pull-out resistance and to ensure good plastic flow as the Insert rotates into the hole. Installation torque to achieve sufficient tension between the threads is not a problem in that the helical knurls are designed so that the direction of the installation torque will have the tendency to drive the Insert into the hole, which of course is not possible, as the threaded joint is tightened.
• •A pilot only slightly smaller than the hole and of sufficient length is designed to assure straight insertion into the hole.
