Product Description
10-32 UNF A2 Stainless Steel Countersunk Slotted Machine Screws
These 10-32 UNF machine screws combine a corrosion-resistant A2 stainless steel construction with a traditional slotted drive and flat countersunk head. Once installed into a suitable countersink, the head sits flush with or below the surrounding surface.
Supplied fully threaded in a selection of imperial lengths, they are suitable for machinery, electrical equipment, automotive work, restoration projects and general engineering applications requiring a neat, low-profile fixing.

Installation Information
Install using a correctly sized flat-bladed screwdriver and a matching 10-32 UNF nut or tapped hole. These fine-thread screws are not compatible with 10-24 UNC components, despite having the same nominal No.10 diameter.
Stainless steel threads can gall when tightened rapidly or without lubrication. For repeated assembly or higher tightening loads, a suitable anti-seize compound is recommended.
