Overview

Hex Set Screws and Flange Bolts for General Engineering in Dubai

In UK and Gulf usage a set screw is a hexagon head screw threaded for its full length, to ISO 4017 or DIN 933. Unlike a part-threaded bolt it can be screwed into tapped holes of any depth and is the general-purpose choice for brackets, machinery and steelwork. A hex flange bolt to EN 1665 (DIN 6921 style) has an integral washer flange, often serrated, that spreads clamping load and grips the surface so the joint resists vibration.

Hamza Fasteners stocks hex set screws from M5 to M24 in grade 8.8 zinc plated, 10.9, hot-dip galvanised and A2 / A4 stainless, together with hex flange bolts in common sizes. They are used in vehicle body building, HVAC supports, conveyor frames, cable tray and pump mounting. Send size, length, grade and finish to our Deira, Dubai counter for a fast price.

FAQ

Common questions

What is a set screw in the UAE?
In UK and Gulf trade terms a set screw is a hexagon head screw threaded all the way to the head (ISO 4017 / DIN 933). In American usage set screw means a headless grub screw, so check which you need when ordering.
When should I use a flange bolt instead of a bolt and washer?
A flange bolt combines the washer and head in one part, speeding assembly and preventing lost washers. Serrated flanges also bite into the surface to resist loosening under vibration, but should not be used on painted or soft surfaces you need to protect.
What sizes of set screws and flange bolts do you stock?
We stock hex set screws from M5 to M24 in common lengths and grades, and hex flange bolts in M6 to M12. Larger sizes and inch threads are available on request.
How much do hex set screws cost in Dubai?
Prices depend on size, length, grade, finish and quantity. Send your list on WhatsApp and Hamza Fasteners will reply with a quotation. Include grade and finish, for example 8.8 zinc or hot-dip galvanised, and whether you need matching nuts and washers.
Do you deliver bolts across the UAE and GCC?
