1/4-20 Phillips Oval Head Machine Screws Stainless Steel Oval heads have a low dome and are tapered for countersinking. Machine Screws are a straight shanked fastener designed to be used in a hole that is pre tapped or a clear hole with a nut on the opposite side. Stainless Steel Machine Screws are used in applications which require general atmospheric corrosion resistance, refrigeration equipment, and food processing machinery. These screws have an approximate Rockwell hardness of B85 - B95 and a minimum Tensile Strength of 80,000 PSI General Product Information Oval Head Screws Length is Measured from the top of the Head to the Tip Head Style : Oval Drive Style : Phillips Drive Size : #3 Thread : 1/4-20 Material : Stainless Steel 18-8 Overall Length : Select Length in Drop Down Menu Quantity of Fasteners in Package : Select Package Quantity in Drop Down Detailed Product Information: Head Diameter : 0.477" Head Height : 0.232" Countersink Angle : 82 Degree Thread Diameter : 0.250" Threads Per Inch (TPI) : 20 Coarse or Fine Thread : UNC Coarse Thread Coverage : Fully Threaded Key Notes: Machine screws are uniformly threaded screws of 1/4" nominal diameter or less that is designed to be threaded into uniformly threaded nuts or threaded holes in the parts they are intended to fasten.

Phillips drive is a cross head design and is the most commonly used type in America. Phillips is often criticized for its tendency to cam out at lower torque levels but this was actually a deliberate feature of the design, for the purpose of assembling aluminum aircraft without overtightening the fasteners. The vast majority of stainless steel fasteners are produced with metals from the austenitic family. Their high levels of chromium and nickel provide tough corrosion resistance and the ability to withstand considerable physical strain without fracturing, albeit at a higher cost than the martensitic varieties. Made of stainless steel grade 18-8 which offers a high level of chemical and corrosion resistance and strength that will out perform and out last all zinc plated fasteners for years with out the need to perform costly and time consuming maintenance.
