Features
- 18-8 Stainless Material
- Flat head with slotted Drive
- Stainless is also superior to steel in withstanding some elevation in application operating temperature while maintaining its strength.
- 12-24 Diameter, 3/4" 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 JFM194SS – Frequently Asked Questions
1) Will a flat head slotted machine screw sit flush in a countersunk hole?
That is what the flat head is for. The head measures 0.38 to 0.412 in. across with a head height of 0.112 to 0.132 in., so it seats flush in an 82 degree countersink of that diameter. If your hole is not countersunk, the head will stand proud and you want a pan or round head instead.
2) Do these stainless machine screws meet Buy American and ARRA requirements for a public job?
Metallics lists the JFM194SS as both Buy American compliant and ARRA compliant. Country of origin is China. Institutional and government buyers writing a domestic-preference spec should read both of those together against the clause in their contract.
3) Is 18-8 stainless the right choice for outdoor or wet-location fastening?
18-8 stainless handles general atmospheric corrosion, which is why these screws turn up in food processing and refrigeration equipment as well as damp electrical work. It also holds strength better than plain steel when the application runs warm. For heavy salt or chemical exposure, 18-8 is not a marine-grade alloy.
4) How many screws come in a jar and can I buy fewer than that?
These ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit. Filled jar weight is 0.76 lbs. Metallics does offer other sizes and quantities in the FM and FMP series by request.
5) What load will a 12-24 stainless machine screw take, and is there a grade marking?
Minimum tensile is 1450 lb with hardness at Rockwell B85-B95. There is no national performance standard for stainless machine screws, so Metallics publishes those figures as a guide rather than a graded rating, and you will not find a head grade marking like you would on a hex cap screw. Dimensions follow ASME B18.6.3-1998 with SAE material.
6) Is a machine screw the right fastener here, or do I need a self-tapping screw?
A machine screw has no point and cuts no thread. The JFM194SS needs a tapped hole or a nut, which is how box and device mounting holes come. If you are fastening into sheet metal or a drilled hole with no thread in it, you want a self-tapping or sheet metal screw, not this.
