The socket (Allen) head sits neatly in a counterbore or recess rather than protruding like a standard hex bolt head, which is why socket cap screws are the usual choice wherever a flush or near-flush finish matters, or where a spanner can't get a clean swing at a protruding head. The hexagon socket also gives a positive, secure fit for the driving tool, which helps when a fixing needs to be driven or removed at higher torque without rounding off the head.\u003c\/p\u003e\n\u003cp\u003eA2 stainless offers good general corrosion resistance and is cost-effective. Driving requires a correctly sized hex\/Allen key matched to the screw diameter - most standard toolkits already cover the common sizes in this range. Several of the longer sizes are partially threaded rather than fully threaded, leaving a smooth shank section near the head for a cleaner bearing surface in clamped joints; M10×70mm is also available

Head diameter, head height and hex socket size all scale precisely with thread diameter, and the deep hex socket takes a standard Allen key: a 2mm key drives the smallest M3 size, rising through 2.5mm, 3mm and 4mm for M4, M5 and M6, up to 5mm for M8 and 6mm for M10. The socket gives a strong, secure drive that resists cam-out far better than a slotted or cross-head fastener.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow-profile button head: a neat, unobtrusive domed head with no corners or edges, ideal where a tidy, low-snag finish matters\u003c\/li\u003e\n\u003cli\u003ePlain head without markings: a clean, decorative look on visible fixings\u003c\/li\u003e\n\u003cli\u003eHex socket drive: excellent grip and torque transfer with a standard Allen key, reducing the risk of cam-out\u003c\/li\u003e\n\u003cli\u003eA2 stainless steel: strong resistance to rust and corrosion for long-lasting performance in indoor and outdoor use\u003c\/li\u003e\n\u003cli\u003eFully threaded: ISO metric thread to ISO 965-1, tolerance class 6g, made to ISO 4759-1 tolerances\u003c\/li\u003e\n\u003cli\u003eSimilar to ISO 7380-1: head and socket dimensions for every thread size are listed in the table below\u003c\/li\u003e\n\u003cli\u003eWide size range: 48 diameter and length combinations from M3 to M10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhy A2 Stainless Steel\u003c\/strong\u003e\u003cbr\u003e\nA2 stainless steel is a general-purpose austenitic stainless alloy prized for its excellent resistance to rust and corrosion in normal indoor and outdoor environments: garden furniture, external cladding, bathrooms and kitchens all benefit from its low-maintenance, hygienic finish.

Black Oxide Hex Socket Countersunk Bolts, DIN 7991 Grade 10.9 Carbon Steel, Allen Key Flat Head Screws, M4x8mm to M8x35mm","description":"\u003cp\u003e\u003cstrong\u003eCountersunk hex socket bolts manufactured to DIN 7991\u003c\/strong\u003e, made from carbon steel to property class 10.9.\u003c\/p\u003e\n\u003cp\u003eThe defining feature is the head geometry: a conical 90° countersunk profile that seats flush with, or just below, the surrounding material once fully driven home, leaving a smooth, snag-free surface rather than a proud bolt head. Drive is via a fully recessed internal hexagon (Allen key) socket, so you can tighten the bolt with an Allen key, straight down the centre of the fastener – useful both for reaching full seating on a hard carbon-steel bolt and for working in a recess too shallow or tight for a spanner or screwdriver.
