Oval Head Machine Screws
Oval head machine screws have a countersunk head with a rounded top surface and a cone-shaped 82 degree bearing surface. The oval style is often preferred over a flat head in conical applications, or when a more decorative look is required. Oval undercut machine screws are similar to the standard oval head style except that the head is undercut 70% of its normal side height. The oval undercut style is standard in shorter lengths because it allows greater length of threads.
