8-32 x 1-1/2 in. Flat Head Phillips Machine Screws - 18-8 Stainless - 100qty
Features
- 18-8 Stainless Material
- Stainless is also superior to steel in withstanding some elevation in application operating temperature while maintaining its strength.
- Flat head with Phillips Drive
- 8-32 Diameter, 1-1/2" Length
- Stainless steel machine screws are used in applications which require general atmospheric corrosion resistance, in food processing machinery and refrigeration equipment.
Additional Notes
- Other sizes and quantities available by request | Hardness and tensile strength standards are offered as guides only for stainless machine screws. There is currently no national standard for these performance requirements for stainless machine screws.

Metallics JFMP88SS – Frequently Asked Questions
1) Are these stainless screws OK for outdoor, damp, or food plant work?
18-8 stainless is the usual pick for general atmospheric corrosion resistance, and this material is specified for food processing machinery and refrigeration equipment as well. It also holds its strength better than plain steel when the application runs warm. For constant salt spray or chlorinated washdown, 316 stainless is the step up.
2) Is a machine screw the right choice here, or do I need a self-tapping or sheet metal screw?
A machine screw like the JFMP88SS has a straight, fully formed 8-32 UNC thread and no point, so it needs a pre-tapped hole or a nut. It will not cut its own thread in sheet steel or drywall. Use it for device boxes, panel covers, equipment brackets and anywhere there is an existing 8-32 tapped hole; reach for a self-drilling or sheet metal screw when the hole is untapped.
3) What size Phillips bit drives these without camming out?
A #2 Phillips. The recess is 0.182 in. in diameter and 0.11 in. deep, which is a #2 profile, so a #1 bit will spin in the recess and chew it up. Stainless galls more easily than plated steel, so keep the bit seated and the speed down.
4) How much load will an 8-32 stainless machine screw take?
Minimum tensile strength is 850 lb, with hardness at Rockwell B85-B95. Note that hardness and tensile figures for stainless machine screws are guides only, since there is no national performance standard for them. Dimensionally the screw is held to ASME B18.6.3-1998 with SAE material grading, so the geometry is to spec even though the strength numbers are advisory.
5) Do these 8-32 x 1-1/2 screws meet Buy American and ARRA requirements for a government job?
The JFMP88SS carries both ARRA Compliant and Buy American Compliant flags in its product data, with country of origin listed as China. If your specification has a domestic melt-and-manufacture clause, verify which compliance pathway your project is using before you submit.
6) How are these sold, loose or in a package, and is there a minimum?
They come in a jar, with a minimum order of 100 count. That makes it a shop or truck-stock item rather than a single-screw buy, which is how most electricians and maintenance crews want 8-32 hardware. Metallics lists other sizes and quantities in the FM and FMP series by request.
7) What does a jar of these 8-32 x 1-1/2 stainless screws weigh and how much shelf space does it take?
Listed product weight is 0.73 lbs, in a container measuring 3 in. length by 3 in. width by 2.7 in. height. Small enough to keep several thread sizes together in a parts bin on the van.
