🔍 Key Concepts

• Screwdriver head designs and how they match different screw recesses • The visual difference between cross-shaped, square/pointed, and star/splined patterns • How torque transmission is improved by multiple parallel ridges or splines

💭 Think About

• Picture each screwdriver tip in your mind: which ones are simply flat or cross-shaped, and which one looks more like a many-pointed star or splined socket? • Ask yourself which design is specifically meant to prevent cam-out (slipping) by having multiple contact points formed by ridges or splines. • Consider which of these names you most often see used with specialty automotive or machinery fasteners that require a star/spline-like driver.

✅ Before You Answer

• Be sure you can visually distinguish a basic cross-shaped tip from one that has multiple star-like ridges. • Confirm which design is known for high torque transfer and reduced slipping due to its splined/star profile. • Eliminate any option that is clearly just a flat blade or a simple cross rather than a ridged, star-like pattern.
