This 3 x 20mm countersunk wood screw is manufactured to DIN 97 in A2 stainless steel (304 grade).

Typical applications
- Traditional and restoration joinery
- Hinges, catches, and door furniture
- Cabinetmaking and period timber work
- General timber fixing where a slotted head is wanted
Available in packs of 10 to 50, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns. For coastal, marine, or chloride-rich environments, Simfix A4 (316 grade) equivalents are available.

How do I choose between A2 and A4 stainless steel?
A2 (304) stainless steel suits most indoor, outdoor and workshop jobs. Choose A4 (316) marine grade for coastal, marine, poolside or other chloride-rich environments.
How do I make sure I order the right size?
Check the size in the product title and the standard, material and dimensions in the Product Specification tab. In M8 x 30, M8 is the thread diameter and 30 is the length in millimetres. See our size guide if you need more help.
When will my order arrive?
Orders placed before 3:30pm Monday-Friday are typically dispatched the same working day and every order is tracked. Next-day delivery is free over £50, or £5.50 below that threshold. Full options are shown at checkout.
