Simulation of a Screw Self-tapping Process
2019With the ever-increasing demand to use lightweight materials in the automotive industry, automakers are keen on using plastics across their products. Plastics are predominantly held together using adhesives, screws, or snaps. Screws are promising when axial reinforcement between the components is desired. Self-tapping screws are now the preferred type,

[Research on Self-tapping Performance Test of Self-tapping Bone Screws].
Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation, 2022To study the self-tapping performance test method of self-tapping bone screws based on the YY/T 1505 standard.With reference to the method of YY/T 1505, various factors affecting the self-tapping force test was optimised, and the self-tapping force judgment method was improved.The experimental results showed that the self-tapping force obtained by the ...

Fatigue & Fracture of Engineering Materials & Structures
To provide more suggestions for the anti‐fatigue design of cold‐formed steel, a series of high‐cycle fatigue tests are carried out on cold‐rolled steel sheets connected by self‐tapping screws and blind rivets in this paper.

Pullout Strength of Self-Tapping Screws Inserted to Different Depths
Journal of Orthopaedic Trauma, 2005The purpose of this study was to determine whether the depth of insertion through the far cortex of self-tapping screws significantly affects pullout strength.Fifty, Synthes, 3.5-mm, self-tapping screws were inserted into synthetic bone blocks and divided into 5 groups. Group 1 had screws with their tips inserted 1 mm short of the far cortex.

Comparison of Compression and Torque Measurements of Self-Tapping and Pretapped Screws
Plastic and Reconstructive Surgery, 1989The choice of an internal fixation system for maxillofacial surgery is made difficult because of lack of information with respect to functional load. This study attempted to clarify some of the controversy with respect to maxillofacial use of these implants. Maximal compressive force to torque values were measured in standardized bone thicknesses of 1,

Journal of Oral and Maxillofacial Surgery, 1990
Multiple systems for internal screw fixation are presently in use in oral and maxillofacial surgery. These systems differ in screw diameter, material, and design. This study evaluated the uniaxial pullout strength of five screw systems. Two-millimeter, 2.7-mm, and 3.5-mm screws were initially evaluated for pullout strength.
