Qlvily 4 Packs 316 Stainless Steel 1/4″ UNC Eye Bolt
Qlvily offers four 1/4″ UNC eye bolts crafted from 316 marine-grade stainless steel. With a maximum load capacity around 220 lb, these shoulder eyebolts are designed for corrosion resistance in challenging environments. The smooth surface and precision-machined threads facilitate straightforward installation, making them a practical choice for marine, outdoor, or workshop lifting tasks. The 316 material ensures better rust resistance than standard stainless, which is beneficial for salt air and humid settings.
QWORK Eye Bolt, 20 Pack 1/4″ – 20 x 1 Marine Grade
This QWORK set includes twenty 1/4″ x 1″ shoulder eyebolts made from corrosion-resistant stainless steel. The smooth eye and precise threading support quick installation, while their elevated count provides bulk options for multiple rigging points or larger projects. They excel in applications requiring steady lifting, anchoring, or tying operations where reliable grip and consistent performance matter. The 304 stainless construction balances cost with good corrosion resistance suitable for many non-marine environments.
Aiwaiufu 4 Packs 1/4″-20 Eye Bolts, 316 Stainless
Aiwaiufu provides four 316 stainless steel eye bolts with a shoulder design and UNC standard threading. The 1/4″-20 thread size pairs with compatible nuts or mounting hardware, and the 316 material contributes superior corrosion resistance in marine or humid environments. The working load hint of 220 lb supports light to moderate lifting and rigging tasks, while the smooth finish aids ease of installation and reduces snag risk during use.
NIDAYE 1/4″ UNC Lifting Shoulder Eye Bolts, 4 Pack
NIDAYE’s set includes four 316 stainless steel shoulder eyebolts with UNC threads. The kit emphasizes a 1/4″ diameter with a common UNC standard, and a working load limit around 220 lb. These bolts offer corrosion resistance and a durable construction suitable for general lifting, rigging, or securing applications. The included design details support straightforward integration with compatible nuts or fixtures, aiding reliability in daily use.
QWORK Shoulder Eye Bolts, 10 Pack 316 Stainless Steel
This QWORK set provides ten 316 stainless steel shoulder eyebolts designed for both straight and angular pulls. The 1/4″ diameter paired with a 2″ length supports more substantial securement and attachment options. With high corrosion resistance, these eyebolts are suitable for marine or harsh outdoor environments. A notable attribute is their 400 lb working load limit for inline pulls, delivering greater capacity for heavier loads while maintaining reliable performance in challenging conditions.
QWORK Threaded Eyebolts, 10 Pack 1/4″ x 2″
This QWORK set focuses on 1/4″ x 2″ long threaded eyebolts, emphasizing durability and ease of installation. Made from stainless steel, the eyebolts are designed to resist rust and corrosion. The kit’s utility spans multiple rigging tasks where ropes, cables, or jaws need a secure anchor, making these ideal for both simple and more complex assembly jobs. The included hardware supports straightforward mounting in beams and uprights for dependable operation.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: For marine or outdoor use, 316 stainless steel offers the best rust resistance; 304 is adequate in general environments where exposure is lower.
- Thread size and compatibility: Ensure both the UNC standard and 1/4″ diameter align with your existing nuts, brackets, or fixtures. Check the thread length to ensure secure engagement.
- Working Load Limit (WLL): Match the WLL to the intended load. For light to moderate lifting, 220 lb is typical for 1/4″ eyebolts; higher capacity (e.g., 400 lb inline) suits heavier loads or more demanding tasks.
- Shoulder design vs. plain eye bolts: Shoulder eyebolts provide better alignment and load distribution for straight or angular pulls. Consider whether you need a flat shoulder for mounting in a fixture or a more compact eye.
- Finish and surface: A smooth finish reduces wear on attached cables or straps and eases cleaning in corrosive environments.
- Pack size and value: Larger packs (like 20 or 10 pieces) are cost-effective for projects requiring multiple fixed points. Smaller sets are suitable for targeted tasks.
- Installation ease: Look for precision-machined threads and smooth surfaces to minimize installation effort and threading cross-talk.
- Accessories included: Some sets come with nuts, washers, or drill bits to support immediate use and secure mounting.
Comparison snapshot
- Best overall corrosion resistance: 316 stainless steel eyebolts perform well in marine and humid environments.
- Best value per unit: Larger packs from QWORK provide lower cost per eyebolt with robust stainless steel construction.
- Best for high inline load: 400 lb WLL eyebolts are suited for heavier inline lifts, as seen in the 1/4″ x 2″ QWORK set.
- Versatility: Shoulder eyebolts support both straight and angular pulls; look for options with a longer threaded shank if spacing is an issue.
These options provide a range of materials, packs, and load capacities to fit common lifting, rigging, and securing tasks. When selecting, prioritize corrosion resistance, proper thread compatibility, and the required working load limit to ensure safe and efficient operation across environments.
