300 pcs cone point set screws — a complete grub screw assortment kit in 304 stainless steel, covering 10 metric sizes from M3 to M8, with 5 matching hex keys and a clear 10-compartment organizer case. The cone point bites into the mating surface for maximum holding power; the internal hex socket takes high torque without cam-out. Headless, fully threaded, made to DIN 914 / ISO 4027. Use them on shaft collars, pulleys and gears, handles and knobs, 3D printers and small machinery. In stock; private label, custom packaging and FNSKU labeling available.

Cone point = the strongest hold. The sharp tip slightly penetrates the mating surface, so the screw resists vibration and lateral movement far better than a flat point — ideal for permanently or semi-permanently locating parts on a shaft. High torque, no cam-out. The internal hex socket accepts a standard Allen key and lets you load real torque without slipping or stripping the drive. Headless, flush, space-saving. Fully threaded with no protruding head, each screw drives completely below the surface for a flush, recessed fit. 304 stainless steel. Excellent rust and corrosion resistance for indoor, outdoor, damp and wash-down environments. Sorted, portable, ready to use. Clear case for instant size ID; 10 separate compartments; 5 hex keys in the same case; compact enough for a toolbox or maintenance kit.

Ideal as headless hex socket set screws for shaft collars, and for stainless steel grub screws for pulleys and gears — plus:

Application	What it does
Shaft collars	Positions and secures collars on shafts
Pulleys & gears	Locks pulleys, gears and sprockets against rotation
Handles & knobs	Fixes handles and knobs onto spindles
3D printers	Secures pulleys, couplings and guide components — cone point grub screws are a common 3D-printer spare
Small machinery	General machine building and repair
Maintenance & DIY	Workshop and home repair kits, retail shelves

Standards & Fit

Manufactured to the DIN 914 / ISO 4027 cone point hex socket set screw configuration — the standard most commonly specified for DIN 914 set screws in M3 to M8. Note: DIN 914 is the cone point type; DIN 916 is the cup point type. They are not interchangeable. If your drawing calls for a cup point or flat point, tell us — we quote those separately.

FAQ

Q1: What is a cone point set screw used for? A: A cone point grub screw has a sharp tip that slightly penetrates the mating surface, so it grips a shaft or spindle very firmly against vibration and lateral movement — the classic choice for headless hex socket set screws for shaft collars, pulleys, gears, handles and knobs in permanent or semi-permanent assemblies.

Q2: What sizes and quantities are included? A: 300 screws in 10 metric sizes — M3×4 (50), M3×6 (50), M4×5 (40), M4×8 (40), M5×5 (30), M5×8 (30), M6×6 (20), M6×10 (20), M8×8 (10), M8×12 (10) — plus 5 hex keys and a 10-compartment case. Please confirm the required thread size before ordering.

Q3: Will the cone point damage my shaft? A: A cone point may leave a small indentation — that indentation is what creates the grip. If marks must be avoided, choose a flat point or nylon-tip set screw; contact us for alternative point styles.

Q4: Which standard and material? A: 304 stainless steel, DIN 914 / ISO 4027 cone point hex socket set screw configuration. Need a different grade (316) or black-oxide alloy steel? That is available as an OEM option.

Q5: Are they in stock? Can we customize for Amazon / EU / US retail? A: In stock and ready to ship. OEM/ODM covers private label, custom packaging, barcode & FNSKU labeling, multilingual inserts, carton marks and in-box assortment. Bulk flow: inquiry → sample → packaging approval → production → shipment.

Q6: Are they suitable for 3D printers? A: Yes — cone point grub screws are widely used on 3D printers for securing pulleys, couplings and guide components. Confirm the thread size and length your machine requires before ordering.
