🏷️ Brand: HomeDIYer Fastener | DIN914 | A2-70 | Corrosion-Resistant | Hex Keys Included
📌 Overview — Precision alignment and locking for shafts, gears, and fixtures. When you need to secure a component without damaging the shaft or provide a precise pivot point, cone point set screws are the answer. Our A2-70 Stainless Steel Cone Point Grub Screws (DIN914) feature a sharp 90° cone tip that fits into pre-drilled conical seats or centers a shaft perfectly. The hex socket drive allows high torque application without cam-out, while the A2 stainless steel construction resists rust and corrosion – ideal for marine equipment, food machinery, outdoor fixtures, and any application where moisture is a concern. Fully threaded from M3 to M8, these screws are also known as socket set screws. We include the correct hex keys with your order. Choose your length – perfect for instrument makers, marine riggers, and industrial maintenance pros.

💡 Length & ordering info: Grub screws have no head – length is measured overall (including the cone tip). Choose your preferred length (e.g., 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 30mm) — sold as per your requirement. Hex keys (Allen wrenches) are included with your order – one key per size or a multi-tool, depending on pack.
🔧 When to use cone point: Use cone point set screws when you need precise positioning, when the screw will seat into a conical depression, or when you want to minimize marring of the shaft surface (compared to cup point). Excellent for instrument adjustment screws, pivot points, and locking into pre-drilled divots.
❓ Frequently Asked Questions – Cone Point Grub Screws
What is the difference between cone point and cup point grub screws?
📐 Cone point has a sharp 90° tip that fits into a conical recess or centers a shaft – ideal for permanent locating and pivot applications. Cup point has a concave cup that bites into the shaft surface for maximum holding power against rotation. Cone point causes less surface damage and is better for softer shafts or when precise alignment is needed.
Are these screws corrosion-resistant for outdoor use?
🌊 Yes – A2-70 stainless steel (304 grade) provides excellent corrosion resistance for outdoor, marine (freshwater and coastal), and humid environments. They will not rust like carbon steel. For continuous saltwater immersion, consider A4 (316) stainless, but A2 is perfect for most exterior and marine hardware applications.
Do you include hex keys? What sizes come with my order?
✅ Yes, the box includes the correct hex (Allen) keys for the screws you order. For example, M3 screws come with a 1.5mm key, M4 with 2mm, M5 with 2.5mm, M6 with 3mm, and M8 with 4mm. You'll have everything needed to install them right away.
What lengths are available? Can I order custom lengths?
📦 “As per Your Choice” – select the exact length you need when ordering. Common lengths range from 4mm up to 30mm (4,5,6,8,10,12,16,20,25,30mm). Custom lengths available for bulk orders – just contact us with your requirements.
How is the screw length measured for grub screws?
📏 For set screws (grub screws), the length is measured overall – from the flat end (top) to the very tip of the cone point. This is standard per DIN 914. Unlike bolts, there is no separate head, so the overall length is the total length of the screw.
