Phillips Flat Head Machine Screws - 100 Degree Taper Black Oxide 18-8 Stainless Steel Thread Size: #6-32Undercut in lengths 3/16" or shorterFastener head sits flush with the installation surfacePrimarily used for thinner materials and extended thread lengthMade of 18-8 Stainless steel with a Black Oxide finish for a durable fastener with a sleek black lookBlack oxide finish gives fasteners a sleek look while adding a layer of protection from abrasion Phillips Flat Head Machine Screws in Black Oxide 18-8 Stainless Steel featuring a 100-degree countersunk head are often used for shorter length fasteners to allow for a greater threaded length. Machine Screws of this style are very similar to a standard Phillips Flat Head Machine Screw, however the countersink underneath the head is shorter in length due to the angle of the taper. Because of this, 100-degree taper screws are often used when fastening thinner materials. Product Specifications: Material: 18-8 Stainless Steel Finish: Black Oxide Diameter: #6 Thread Size: #6-32 Drive Style: Phillips Drive Size: #2 Head Style: Flat Countersink: 100 Degrees Head Diameter: Max 0.262 - Min 0.238 Head Height: Max 0.059 - Min 0.048 Thread Pitch: 32 per inch Thread Type: UNC (Coarse) Phillips Flat Head Machine Screws - Black Oxide 18-8 Stainless Steel Black Oxide 18-8 Stainless Steel Machine screws in this selection are made of 18-8 stainless steel, with a black oxide finish. Black Oxide Fasteners made from stainless steel, have been chemically treated to alter certain qualities of the material, most notably the color. The treatment also adds a mild corrosion and abrasion resistance (in addition to the plain stainless steel’s nature), and reduces the now black oxide stainless steel fastener’s reflective properties. 100 Degree Tapered Countersink Machine Screws in this selection feature a flat head which is countersunk into the installation surface for a smooth flush finish. These screws are very similar to the standard Phillips Flat Head Machine Screw, however the angle of the taper or the countersink below the head is 100 degrees instead of the standard 82. This feature allows for less of a countersink in the installation, which makes 100 degree countersunk screws ideal for use on thinner materials, and also allows for more threads on the fastener, which increases its holding strength. Common Uses 100 Degree taper screws are commonly used when fastening thinner materials.
