M8 x 70mm Socket Cap Allen Bolts by OUSCHR
Product overview: 10-piece set of M8 bolts with a Black Oxide exterior finish. Exterior features include a right-hand thread, partial threading, and a hex socket drive of 5 mm. The bolts have a head diameter of 16 mm and a head height of 3.2 mm, suitable for furniture and mechanical assemblies where a low-profile head is preferred. The thread pitch is 1.25 mm, aligning with standard M8 fasteners used in many DIY and professional contexts.
Key references: Thread diameter 8 mm; screw length 70 mm; head diameter 16 mm; drive type hex socket. The black oxide finish provides moderate corrosion resistance and a subdued appearance. The set is ideal for users seeking a compact, robust fastener with reliable torque transfer in light-to-medium duty applications. Warnings include ensuring compatible nuts and washers and verifying material compatibility with surrounding components.
uxcell M8 x 70mm Hex Head Screws Kit
Product overview: A 4-set kit including bolts, nuts, flat washers, and lock washers. Threads are M8 x 70 mm with external hex drive grooves for uniform torque transfer and locking efficiency. Made of 304 stainless steel, these connectors offer improved hardness and corrosion resistance, particularly in moisture-prone environments. Installation requires a wrench (not included) for secure assembly.
Key references: Fully threaded bolts, clean mechanical threads, and stainless steel construction for rust resistance. The set is well-suited for furniture assembly, machinery fixtures, and automotive components where corrosion resistance and repeatable torque are important. Consider potential stainless steel galvanic concerns with other metals in the assembly and ensure proper torque specs are followed to prevent thread stripping.
M8-1.25 x 70mm Plain Finish Frame Bolt
Product overview: Plain finish steel frame bolts in a Din 6921 standard with a 1.25 mm thread pitch. These hex flange bolts emphasize construction-grade durability, intended for automotive fittings, agricultural machinery, and other heavy-duty projects. The 70 mm length supports deeper thread engagement for secure fastenings in frames and assemblies requiring robust clamping.
Key references: 10.9 class equivalents (as noted in typical Din 6921 context) provide high tensile strength for demanding applications. The plain finish supports straightforward installation in non-corrosive indoor environments or protected outdoor setups. As with any frame bolt, compatibility with nuts and washers is essential to maximize load distribution and minimize loosening risks under vibration.
VGBUY M8-1.25 x 70mm Bolts Kit
Product overview: A 12-piece set of M8 bolts with 1.25 mm pitch, full thread, and black zinc plating for enhanced corrosion resistance. The kit includes an extra hex spanner, adding value for quick installation. Made from 304 stainless steel, these fasteners balance strength with resistance to rust and chemical exposure. The phosphated black finish reduces glare and adds a modest aesthetic suitable for many projects.
Key references: Deep, clear threads and a robust hex socket drive provide reliable torque transfer. The stainless-steel base material enhances longevity in humid or outdoor conditions, while the black zinc coating offers surface protection. Users should verify compatibility with accompanying nuts and washers and follow appropriate torque values to avoid over-tightening and thread damage.
iexcell 25 Pcs M5 x 70mm Stainless Kit
Product overview: Although this kit centers on M5 bolts, it demonstrates the variety of 70 mm length options offered by ixcell. The set features 25 pieces with 0.8 mm thread pitch, stainless steel 304, and a hex socket drive. It includes a hex key for convenient driving and demonstrates common packaging that complements larger M8 options for mixed-material projects.
Key references: Button and socket head variants illustrate how different head styles contribute to flush mounting and aesthetic matching in furniture or machinery assemblies. When pairing with M8 hardware, ensure thread sizes and pitch align, and consult load requirements and material compatibility for multispecies assemblies to prevent galvanic corrosion or mismatched torque loads.
MewuDecor M8 x 70mm Socket Head Screws
Product overview: 10-piece set of 100% stainless steel A2-70 socket head cap screws. Full thread, bright finish, and a metric 8 mm diameter with 70 mm length. The Allen drive is sized for a robust torque transfer, making these suitable for machine parts, furniture joints, and heavy-duty assemblies where corrosion resistance and ease of disassembly matter. The A2-70 grade offers good chemical resistance and mechanical properties for indoor and moderate outdoor use.
Key references: Head diameter and height, drive type, and full-thread profile ensure strong clamping and predictable performance under load. The stainless steel construction minimizes rust in damp environments, while the bright finish simplifies visual inspection. For best results, use compatible nuts and washers and follow torque guidelines to avoid thread damage or loosening over time.
Buying Guide: Key Considerations For 70 x 0.8 Mm Fasteners
- Material selection: Stainless steel (304/A2-70) offers corrosion resistance, while carbon steel with zinc or black oxide finishes improves wear resistance and reduces visibility in furniture or machinery applications.
- Thread pitch and length: Ensure pitch matches your nut and threaded hole specifications (0.8 mm or 1.25 mm are common for M8 studs). Confirm head type and length align with surface clearance and load paths.
- Head style and drive: Socket cap, button head, or flange bolts affect flush mounting and access. Hex socket drives are standard for tight torques; consider low-profile heads when surface clearance matters.
- Finish and coating: Oxide, zinc plating, or passivation influence longevity in moisture, salt exposure, or cleaning environments. Be mindful of galvanic corrosion when mixing metals.
- Compatibility: Verify nut type, washer size, and bolt grade. For high-torque or vibration-prone applications, consider lock washers or thread-locking compounds as needed.
- Applications: Choose based on environment—indoor furniture, automotive assemblies, or equipment frames. Full-thread vs partial-thread affects clamping length and shear resistance.
- Packaging and quantity: Kits with extra tools (hex keys) offer value for DIY projects. Review whether you need more bolts of the same length and pitch for consistency.
